________________________________________________________________________________________________________________________________________________
1 Introduction
The Landolt-Börnstein volume number IV/13A, 2006 edition, contains vapor-liquid equilibrium (VLE) data
for 3316 binary subcritical systems of nonelectrolytes. Equilibrium temperature T, pressure P, liquid x1,
and vapour y1 mole fraction compositions are reported. Seventeen property types are distinguished
depending on whether none, one, or several among the physical quantities P, T , x1, or y1 is kept constant in
the particular data file: isobaric (constant P), isothermal (constant T), isoplethal (constant x1 or y1).
The printed volume contains tables and graphs reproducing some representative data for 802 selected
mixtures. The property type, including the physical quantities with their SI units, the state of the chemical
system, and the method used to obtain the data, the molecular formulae, names and CAS registry numbers
of the components, and the full reference to the original source of data are given. The original units have
been all converted into SI units. When the number of direct experimental data points reported in the original
source is very large (usually more than 50) then part of those data do not appear in the numerical table.
More data may appear in graphical form. In any case, this is marked in the footnote of the tables as “See
SELF for the totality of data”. The footnote gives merely an overall estimate of the uncertainties of the
variable physical quantities.
The ELBT Program on the CD permits to search, display, and print all the 3316 data sets in three
formats:
1. The PDF Display has the same format as the printed version and can be viewed and printed as a PDF
file. It may not show all the direct experimental data. On the graph, the dotted line joining the experimental
points is not a calculated best-fit, but a ‘hand-drawn’ curve.
2. The SELF (Standard ELectronic File) Display is an ASCII file containing all the numerical data in a
well-defined format and SI units. The absolute uncertainties are specified individually for each measured
physical quantity. The Digital Object Identifiers (DOI) of property type, chemical system and reference are
given. The corresponding DOI descriptors are included on the CD in three distinct files. Using these files
and knowing the SELF format, the data can be transferred to databases and application programs.
3. The ELDATA Display is an ASCII file containing all the numerical data in the same format as SELF.
This file is more explicit than SELF, the DOIs of property type, chemical system and reference being
replaced by the corresponding descriptors. Moreover, the ELBT Program permits to convert in advance the
SI units of pressure, temperature and energy into several practical units.
For most of the property types, the ELBT Program allows the Graphical Display of the VLE data,
usually as a function of x1, y1, P, or T, with possible unit conversions. All the experimental points are
displayed, but individually for each data set (isobaric, isothermal, or isoplethal). The ELBT Program
permits in some cases to correlate the isothermal experimental data points by means of the Redlch-Kister
equation using up to nine adjustable coefficients. The values of the regression coefficients are displayed
together with the corresponding standard errors and with the overall standard deviation and the maximum
deviation of the fit. The graph displays the calculated curve. The results of the calculation may be saved in a
separate file.
The ELBT Program allows importing the information of SELF and ELDATA files, as well as of the
files containing the results of correlations into SpreadsheetML documents. The XML files can be viewed
by means of Microsoft  Office Excel 2002 or later.
The ELBT Program on the CD includes a large, almost exhaustive, bibliographical database,
EVLM’2006, giving references to experimental VLE measurements for 2- to 9-component systems. These
components are molecular substances, both organic and inorganic having well-defined molecular formulae.
Aqueous and non-aqueous systems of organic or inorganic electrolytes, ionic liquids, alloy and fused salt
systems, polymers and other materials are partly covered in the database.
The principal features of EVLM’2006 are listed below:

3.1 Physical quantities and physico-chemical properties
The tables in this volume refer to four physical quantities: P - pressure, T - temperature, x1 - mole fraction
of component 1 in liquid phase, and y1 - mole fraction of component 1 in vapor phase. The pure
component liquid molar volumes Vi and the second molar virial coefficients Bij are auxiliary quantities
E
used in calculating GE – the molar excess Gibbs energy, Gi – the partial molar excess Gibbs energies,
∞
and γ i – the activity coefficients at infinite dilution. They are all intensive quantities, i. e. their
magnitudes are independent of the extent of the chemical system.
The physico-chemical properties are functional relationships between these quantities, e. g. P (x1) at
constant T, or P (T) at constant x1, etc.
3.1.1 Independent variables and dependent variables
Generally, each property type is characterized by a group of 'independent variables' and a group of
'dependent variables'. There must be at least one independent variable and one dependent variable.
In the 17 property types of this volume P, T, or y1 is the dependent variable. In the property types
EVLM1111, EVLM1112, EVLM1121, EVLM1131, EVLM 1211, EVLM 1221, EVLM1222, EVLM1231,
and EVLM1232, the independent variable is x1. In the property types EVLM1141 and EVLM1241 the
independent variable is y1. In the property types EVLM1311 and EVLM1321 the independent variable is T.
In the property type EVLM1341 the independent variable is P. In the property types EVLM1411 and
EVLM1431 the independent variables are T and x1. In the property type EVLM1421 the independent
variables are T and y1
3.1.2 Parameters
Generally, in the case of physico-chemical properties consisting of three or more physical quantities, all
the physical quantities remaining after selecting the independent and the dependent variables are
considered as 'parameters', if they take one or several discrete constant values. E. g. in the property
types EVLM1111 and EVLM1211 the parameters are, respectively, T and P. In the property types
EVLM1311 and EVLM1321 the parameters are, respectively, x1 and y1. In the property types
EVLM1411, EVLM14211, and EVLM1431 all the physical quantities are variables.
3.2 Symbols, units and scales of physical quantities
In PDF files the symbols used for pressure, temperature, and mole fractions are those recommended by
IUPAC.
The symbols [X1], [X2], etc. used for independent variables, [Y1], [Y2], etc. used for dependent
variables, and [P1], [P2], etc. used for parameters in SELF and ELDATA files, are functional symbols
having nothing in common with the physical symbols.
All the physical quantities are reported in SI units (product or quotient of SI base units), without
multiple or submultiple prefixes. So there is no need to specify the unit in the SELFs.
Whenever necessary, values taken from the literature have been converted into SI units using the
appropriate conversion factors. Temperatures are based on the International Temperature Scale of 1990
(ITS-90). The molar quantities are based on the 2005 table of the IUPAC Commission on Atomic
Weights and Isotopic Abundances. The standard atomic weights apply to elements as they exist naturally
on Earth (natural abundance of the stable nuclides).

_______________________________________________________________________________________________________________________________________________
The year of publication of a SELF appears in the SELF name. If it differs from the year of publication of
the original source of data, then temperatures and molar quantities should be converted to the abovementioned scales. The corrections being within the limits of uncertainties of the measured quantities they
were not applied to the data reported in this volume.

The property type identifier determines unambiguously the state, all the physical quantities and their quality
(dependent variable, independent variable, or parameter), and the method. The descriptors of the five property
types are shown in Table 1 and are stored in the same directory as the Program as ELBT13APropTypes.txt
file.
3.3 Property types
Seventeen property types are distinguished in the Landolt-Börnstein volume numbers IV/13A, 2006 edition,
(Table 1). All refer to binary single-phase or two-phase liquid-liquid systems in equilibrium with vapor
(State). The vapour-liquid equilibrium data were obtained by direct experimental measurements (Method).

4 Primary search option: chemical system
Each chemical system consists of two or several (maximum 9) components. Each component is either a pure
substance, e.g., ethanol, C2H6O, or an undefined isomer or mixture of isomers, e.g., dimethylbenzene,
C8H10, with well defined molecular formulae, or a material, i.e., a substance or mixture of substances with
undefined molecular formulae, e.g., poly(vinylacetate), air, gasoline, etc. In the bibliographical database the
generic name of a class of substances may appear as a component, e.g., naphtenes, dextrans, etc. Numerical
data are available only for binary systems of pure substances.
4.1 Nomenclature of substances
In general, for each substance an unambiguous and unique name was chosen as the main name (i.e. preferred
name). For organic substances, it is usually one among the various systematic names recommended by
IUPAC. For inorganic substances, the practices approved by the ACS Committee on Nomenclature were
usually followed. The element S is spelled sulfur. A few other systematic names and widely used trivial
names and abbreviations were adopted as synonyms (alternate names).
An attempt has been made to select the main names and synonyms as far as possible in a consistent way.
The following examples illustrate some typical cases of main names, of selected synonyms, and of
unselected synonyms:
Main name
Heptane
1,2-Dimethylbenzene
tert-Butyl methyl ether

4.2 Typing the chemical name of substances
You may use upper or lower case letters when typing chemical names. These are all converted by Program to
upper case. Greek letters are typed as follows:
.ALPHA.
.BETA.
.GAMMA.
.EPSILON.
After typing a name, you have to specify whether it is a Complete Name or a Partial Name (i.e., just a portion
of the Complete Name).
Example:
Typed Text
Partial Name
Displayed
formula
Displayed
main name
TETRACHLORO
C Cl4
C2 H2 Cl4
C2 Cl4
Cl4 Sn
Tetrachloromethane
1,1,2,2-Tetrachloroethane
Tetrachloroethene
Tin tetrachloride
In both cases, the Program displays either a No Component found message or all the main names and
synonyms containing a fragment matching the typed text.
4.3 Symbols of natural elements and nuclides
Natural Elements: The symbols used to denote the natural elements are those recommended by IUPAC.
Nuclides: The symbol used to denote a specific nuclide in the formula of an isotopically modified substance
consists of the atomic symbol of the natural element and an Arabic numeral indicating the mass number of
the nuclide in the left position. Example: 12C. For the hydrogen isotopes with mass numbers 1 (protium), 2
(deuterium), 3 (tritium), the symbols 1H, 2H, and 3H, respectively, are used (the symbols D, T, d, t are not
used at all in formulae).

4.4 Standard order of arrangement of elements in molecular formulae
For substances not containing C atoms, the elements are arranged in the alphabetical order of their chemical
symbols with an Arabic numeral indicating the number of atoms of each element (if different from 1).
Examples:
Cl H
Hydrogen chloride
N2 O
Dinitrogen oxide
For substances containing C atoms but no H atoms, the elements are arranged in the following order: C, followed
by the other elements in the alphabetical order of their chemical symbols with an Arabic numeral indicating the
number of atoms of each element (if different from 1).
Examples:
C S2
Carbon disulfide
C Cl2 F2
Dichlorodifluoromethane
For substances containing C atoms and H atoms, the elements are arranged in the following order: C, H, followed by
the other elements in the alphabetical order of their chemical symbols with an Arabic numeral indicating the number
of atoms of each element (if different from 1).
Examples:
C2 H Br Cl F3
Bromochloro-1,1,1-trifluoroethane
C4 H7 N O
Pyrrolidin-2-one
For isotopically modified substances, the symbol of a nuclide occupies the same place in the formula as the natural
element.
Examples:
(2H)2 O
(2H2)Dihydrogen oxide
C (2H) Cl3
Trichloro(2H)methane
When the isotopically unmodified atomic symbol and one or several modified atomic symbols occur in the same
place in the formula, then the atomic symbol precedes the nuclide symbols, the latter being written in the order of
increasing mass number.
Examples:
(1H) (2H)
(1H,2H)Hydrogen
C H (2H)3 O
(2H3)Methanol
4.5 Typing the molecular formula of substances
The symbols of the constitutive elements followed by the corresponding number of atoms may be typed in any
desired order. To avoid ambiguities, type all the symbols with the usual upper and lower case letters.

The Program may correct unusually typed symbols in some cases. The same symbol may appear several times
in the formula. Spaces left between symbol characters and numbers are ignored. The Program sums up the
elements and arranges them in the standard order of arrangement of elements in molecular formulae.
Examples:

clh or Clh or hcl or HCl
CO or OC or oc
Co or co
h4c or CH4 or ch4 or Ch4 or chhhh
brCH2CH2CH3
Cl H

C H4
C3 H7 Br
Nuclide symbols must be written in parentheses with the atomic symbol of the element preceded by an Arabic
numeral indicating the atomic mass number of the nuclide.
Examples:
Typed txt
Display
(2h)2o or (2H)O(2H)
CCl3(2H)

Typing erroneous symbols or symbols of elements not included in the data base results in a Syntax Error in
Formula message.
After typing a formula, you have to specify whether it is a Complete Formula or a Partial Formula (i.e.,
containing all the elements or only part of the elements).
Examples:

5 Primary search option: reference by author(s)
The full citation of a reference comprises the name(s) with initials of the author(s), the title of the article, the
abbreviation of the original data source, the year of publication, the volume number (if any), the issue number
in parentheses (if necessary), and the first and last page numbers of the article. The Chemical Abstracts
accession number is supplied when available.
5.1 Identification of authors
The name of an author consists of the family name (one or several words), a comma, and the initial(s) of the
forname(s). The family name and the comma, but a single comma, must appear in the name.
All the names are printed in the Roman alphabet. Modified letters and letters with diacritical marks are
printed as their unmodified equivalents except ä, ö, and ü which are transliterated as ae, oe, and ue, respectively.
Names printed in non-Roman alphabets or ideographs are romanized according to the systems used in Chemical
Abstracts.
It often happens that an author publishes under different names either as a consequence of a change of name
or simply because names are not spelled identically in different publications. In order to retrieve all the papers
of an author, independent of how his name appears in the publication, the alternate names were recorded as
synonym names, provided there was no doubt that they do really correspond to the same author. Even slight
differences are taken into account.

6.1 Identification of data sources
Each data source is characterized by an unambigous abbreviation, an internal code, and a SELF identifier.
The abbreviation of a serial publication is usually the same as in Chemical Abstracts and is based on a
standard of the International Organization of Standardization (ISO 4-1972(E)). For non-serial publications
or when the Chemical Abstracts abbreviation could not be identified, an abbreviation was constructed in
the same style.
The internal code used for a serial publication is usually the six-character CODEN (American Chemical
Society International CODEN Directory). For non-serial publications or when the CODEN could not be
identified, a CODEN-like Code (000 followed by three other characters) was defined.
The SELF identifier of serial publications for which the International Standard Serial Number (ISSN) is
available consists of the ISSN preceded by the character S. The SELF identifier of dissertations and Ph. D.
Theses consists of an ISSN-like code preceded by the letter T.
Examples:

menu (Fig. 43).
Fig. 43. Select the display format of numerical data
9.1 PDF display
The PDF (Portable Document Format) display presents the numerical data in a rather traditional tabular
and graphical form similar to the tables printed in the book. In addition, the property type descriptor (see
Chap. 3.3) appears on the top of the table (Fig. 44). It includes the physical quantities with their SI units,
the state of the chemical system, and the method used to obtain the data. The molecular formulae, primary
names, and CAS registry numbers of the components are given. The full reference to the original source of
data is given with the author(s) and the title of the publication.
The states (of aggregation) of the chemical systems of this volume are as follows: each pure component
is a liquid (subcritical fluid); the binary system is either a single-phase liquid or a two-phase liquid-liquid
system. Two-phase regions are clearly marked on the PDF tables.
The original units of the physical quantities have all been converted into SI units. When the number of
direct experimental data points reported in the original source is very large (usually more than 50), then part
of the data do not appear in the numerical PDF table. More data may appear in graphical form. In any case,
this is marked in the footnote of the tables as “See SELF for the totality of data” (Fig. 44).
The footnote gives merely an overall estimate of the uncertainties of the main physical quantities,
usually of x1 , y1 , P, and/or T (Chap. 9.2.2).
On the graph, the dotted line joining the experimental points is not a calculated best-fit, but a ‘handdrawn’ curve.

9.2 SELF (Standard ELectronic File) display
The concept of a Standard ELectronic File (SELF) format has been developed in 1998-2002 by the Task
Group on Standard Physico-Chemical Data Formats (IUCOSPED) of the International Union of Pure
and Applied Chemistry (IUPAC) and the Committee on Data for Science and Technology (CODATA)
in cooperation with the International Council of Scientific and Technical Information (ICSTI). A data
portal, called DataExplorer (FIZ - Karlsruhe), implemented SELFs for a variety of physico-chemical
properties. The structure of the ELBT SELFs follows the general format of IUCOSPED SELFs.
9.2.1 SELF structure. Identifiers
Each SELF consists of two sections:
(1) The header - contains four Digital Object Identifiers (DOIs) for: SELF name, property type, original
source data, and chemical system; (2) the body - contains the numerical data and eventually some
auxiliary identifiers.

9.2.2 Numerical data and estimated uncertainties
In the body of the SELF or ELDATA file of a property type including parameters, [NP] represents the
number of parameter sets (not the number of parameters) and [NX1] the number of data points in each set
(block) of parameters. The numerical values are expressed in engineering style, starting with either a space,
in case of positive values, or the - (minus) sign in the case of negative values, followed by a decimal point,
then usually by six digits, the letter E for exponent (base 10), a + (plus) or - (minus) sign, and two digits
which indicate the power of 10.
In the data files each measured physical quantity is accompanied by its absolute uncertainty. The symbols:
[EX1], [EX2], etc. and [EY1], [EY2], etc. are used, respectively, for the independent and the
dependent variables. The uncertainties are expressed by a decimal point, followed by two digits, the letter E
for exponential (base 10), a + (plus) or - (minus) sign, and two digits which indicate the power of 10 (see
example, Fig. 3.6).

New Series IV/13A

Instructions on Using the ELBT Program on the CD
Chap. 9.3
________________________________________________________________________________________________________________________________________________
Two uncertainties assigned to parameters: [EPC1], [EPC2], etc. express the reproducibility of the
'constant' values of the parameters. [EPA1], [EPA2], etc. express the absolute experimental uncertainty
of the parameters. In the example on Fig. 49, [P1] .906900E+02[EP1C].10E-01[EP1A].20E01 means the measurements are isothermal to within [EP1C] .10E-01 (0.01 K), but the ITS-90
temperature itself, [P1] .906900E+02 (90.69 K), is known with an accuracy of only [EP1A]
.20E-01 (0.02 K).
The uncertainties of the different quantities, if reported by the authors, are given in the SELFs and
identically in the corresponding ELDATA files. In many cases additions and corrections were necessary. In
view of the difficulty of assigning the uncertainties for this type of measurements, the reported values
should be regarded as rough estimates and used with care.
In the footnote of the PDF tables only estimates of the overall uncertainties of the variable physical
quantities, usually of x1, P, T, and y1, are given in terms of ı(x1 ), ı(P), ı(T ), and ı(y1 ), the average
absolute uncertainties, or ırel(P), the average relative uncertainty of P , or more generally of ı(P)/103Pa =
a + b |P/103Pa |, the average absolute uncertainty of P (where b may be equal to zero).
9.2.3 Two-phase liquid- liquid systems
In the case of two-phase liquid- liquid systems the data are presented in the body of a SELF or ELDATA
file in five distinct blocks. This is marked by [NB] 5.
In the example Fig. 49, for the parameter value [P1] .906900E+02 (90.69 K):
the first block contains [NX1]
6 data points in the homogeneous region at mole fractions of
component 1 from [X1] .000000E+00 (x1 = 0.0000) to [X1] .083800E+00 (x1 = 0.0838);
the fifth block contains [NX1]
3 data points in the homogeneous region at mole fractions of
component 1 from [X1] .970300E+00 (x1 = 0.9703) to [X1] .100000E+01 (x1 = 1.0000);
the third block contains [NX1]
10 data points in the heterogeneous region at mole fractions of
component 1 from [X1] .135400E+00 (x1 = 0.1354) to [X1] .950500E+00 (x1 = 0.9505). In this
region P is constant, within the limits of experimental errors.
the second and fourth blocks contain [NX1] 1 data point each, which are the P values on the twophase liquid-liquid equilibrium phase boundary curve at mole fractions of component 1 [X1]
.110000E+00 (x1 = 0.1100) and [X1] .960000E+00 (x1 = 0.9600).
In case of absence of data in a block, [NX1] 0.
9.2.4 Linked data files
Linked data files contain data for a given system corresponding to different property types, which were
obtained in the same apparatus and are reported in the same publication. E. g. the file in Fig. 45, file
number LB0173, property type EVLM1211, contains isobaric x1-T data. This file is linked to another
numerical data file, file number LB0175, containing isobaric x1-y1 data for the same mixture at the same
pressure P, property type EVLM1221. The source of data is the same.
9.3 ELDATA display
The ELDATA (ELectronic DATA) display is an ASCII file containing all the numerical data in a format
similar to, but more explicit, than SELF (Chap. 9.2). Like in SELF, all the data points are displayed with
their uncertainties. Additionally, the descriptors of the DOIs of property type, chemical system and
reference appear in the file. In the case of two-phase systems, the data blocks are clearly shown.
In PDF and SELF the physical quantities are displayed in SI units and no change of units is possible.
The ELDATA display permits the conversion of the SI scale and unit of temperature and of the unit of
pressure, into several practical units (Chap. 9.5).

9.6 Correlating experimental data
The ELBT.EXE program on the CD-ROM allows the correlation of the isothermal experimental P(x1) data,
property types EVLM1111, EVLM1112, and EVLM1131, of completely miscible systems assuming an
excess molar Gibbs energy GE model for the liquid mixture and accounting for vapor phase nonideality
. In this volume, the Redlich-Kister equation, Eq. (3), identifier RK2XMIN1, has been selected among the
various equations which have been proposed for GE. The partial molar excess excess Gibbs energies, µiE,
Eqs. (4) and (5), the total vapor pressure P, Eq. (6), the vapor phase composition y1, Eq. (7), the excess

The general relationships between GE, µiE, and the activity coefficients
γ i∞ are:
G E = ∑i xi µiE

For a binary system the Redlich-Kister equation:
n

G / RT = ∑ A ( x − x )
i 1

i =1
where n is the number of adjustable parameters Ai yields:

accounted for through the second molar virial coefficients Bij and the molar volumes Vi under saturation
pressure.
The correlated total vapor pressure P and the vapor composition yi are given by:

P = ∑ xi Pio exp{[ µiE − ( Bii − Vio )( P − Pio ) − 2 PB12
(1 − y i ) 2 ] / RT }

(7)
where
E
B12
= B12 − ( B11 + B22 ) / 2 ;
Pio = Pexp ( x i = 1)
(8)
The activity coefficients at infinite dilution, Ȗ1∞ and Ȗ2∞ , are given by:
n
ln Ȗ1∞ = µ1E ( x1 = 0) / RT = A1 + ∑ ( −1) i Ai
(9)
i =2
n
ln Ȗ2∞ = µ2E ( x2 = 0) / RT = A1 + ∑ Ai

All the auxiliary values, Bij and Vi , are either experimental data or they may be estimated using known
prediction methods. This expression is sufficient enough for most cases, except for particular systems
where real behavior of vapor phase is due to other reasons, namely association (e. g., in systems containing
carboxylic acids).

9.8 Creating SpreadsheetML documents
The ELBT.EXE program allows importing the information of SELF and ELDATA files, as well as of the files
containing the results of correlations into SpreadsheetML documents.
After selecting the numerical data file LBnnnn, choose the menu entry File command (Fig. 5) and select from
the dialog box (Fig. 59) the XML File/ELDATA or XML File/SELF format.
Fig. 59 Select the XML display format of numerical data
file (ELDATA or SELF)
Fig. 60 Select the XML display format of calculated
numerical data file
Alternatively, after selecting the set of correlated data, choose the menu entry File/XML File/Vapor-liquid
equilibrium or File/XML File /Excess Gibbs energies command (Fig. 60).
The files can be saved in a user-defined directory. The default names are LBnnnn_S.XML for the SELF display
of the primary data, LBnnnn_E.XML for the ELDATA display of the primary data, LBnnnnVLC.XML, for the
calculated vapor-liquid equilibrium data, and LBnnnnGEC.XML for the calculated excess Gibbs energy data.
The XML files can be viewed by means of MicrosoftOffice Excel 2002 or later. An example is shown in Fig.
61.
10 Extraction of bibliographic data
The numerical data files of this volume refer only to 3316 binary systems of 547 substances (nonelectrolytes) and
1142 literature references.
The bibliographical database of the ELBT.EXE program on the CD of this volume is much more
comprehensive, giving 13476 references to experimental vapor-liquid equilibrium measurements published in the
period 1888 – mid 2006 for 20937 two- to nine-component systems. These altogether 3230 components are
organic or inorganic electrolytes and nonelectrolytes, ionic liquids, alloys, fused salts, polymers and other
materials.
As shown in Chaps. 2.2 (Fig. 5), 3.4 (Figs. 9 and 12), 4.7 (Figs. 27 and 28), and 5.3 (Figs. 33 and 34), the
numerical data files which are available in this volume, IV/13A, can be displayed from the Data menu after having
selected a specific data file. By choosing the Extract menu, instead of the Data menu, the Program extracts the
bibliographic data from the database (Chap. 10.1).
Bibliographic data can be extracted from the database even in absence of numerical data by choosing Extract
from the main menu after any single or multiple search option: Find / Properties (Chap. 10.2), Find / Systems
(Chap. 10.3), or Find / References (Chap. 10.4),
Restricting the search to only one or two options, the Program extracts from the database a list with all the
corresponding bibliographic data. The bibliographic data file is structured depending on the sequence in which the
search options were selected.
