Re: Standard subdivisions: Ripple effects of revised rules in Table 1
This exhibit includes an update to the introductory matter at the beginning of Table 1, plus substantial changes to the references, instructions, and content associated with the three internal add tables in Table 1.
On further reflection, we decided to move the note about the special nature of Table 1 add table notation that we had originally planned to include only in the introduction to Table 1 to each of the table records with add tables. Also, to eliminate any confusion about the nature of the special notation, we removed the instruction to follow the table of preference at the beginning of Table 1 and instead introduced a table of preference preceding each add table.
Changes are indicated by strikethroughs and underlining.

The following notation is never used alone, but may be used as required with any regular schedule number, e.g., workbooks (--076 in this table) in arithmetic (513): 513.076. When adding to a number from the schedules, always insert a decimal point between the third and fourth digits of the complete number. Unless other instructions are given, the terminal zeros in a main class or division number should be dropped before adding a standard subdivision, e.g., journals (--05 in this table) in mathematics (510 minus the final zero): 510.5. (Full instructions on the use of standard subdivisions are found in the Introduction to the Dewey Decimal
Classification)
Standard subdivisions should be added only when the work in hand covers the whole, or approximately the whole, subject of the number in the schedules
When standard subdivision notation from Table 1 is listed in Tables 2 through 6 and in the schedules, all of its the notation’s notes and subdivisions as given in this table are applicable unless other instructions are givenmay be used. Other Table 1 notation that is not listed in the schedules may also be used. For example, the fact that 610.7, but not 610.8 or the subdivisions of
610.7, is listed does not exclude the use of 610.71 610.8 or 610.71610.8
Do not add one standard subdivision to another standard subdivision unless specificallyspecially instructed. Standard subdivisions may be added to special notation listed in the regular standard subdivision sequence, to subdivisions of –04 Special topics where specifically listed in the schedules, and to displaced standard subdivisions wherever they appear. Numbers in the schedules that look as though they were built with notation from this table but are outside the regular sequence of standard subdivisionshave headings with a broader or different meanings are not considered "standard" subdivisions. Hence notation from Table 1 may be added to such schedule numbers
Never use more than one zero in applying a standard subdivision unless instructed to do so. If more than one zero is needed, the number of zeros is always indicated in the schedules. If the 0 subdivisions of a number in a schedule are used for special purposes, use notation 001-009 for standard subdivisions; if the 00 subdivisions also are used for special purposes, use notation
0001-0009 for standard subdivisions
