bibliotek.dk in Google


What is bibliotek.dk?
Why consider Google as an access point?
Google Scholar project
Google Books
Google
bibliotek.dk – in short






End-user-version of the national union catalog DanBib
Access to 10 million records
Request facilities to all Danish libraries (1.38 million
requests in 2005)
Up to 100.000 visits per week
Funded by the Danish state
Developed and hosted by the
Danish Bibliographic Centre Dansk BiblioteksCenter.
Records in Google? – why?



Users to whom libraries are not the
obvious choice might find it
Visibility to information seekers
when they don’t think of libraries
To brand the libraries as a quality
resource centre.
First project: Google Scholar


Because that was Google’s choice
Google Scholar is tuned for that
(they thought – we thought..) –
Format – export/harvesting




You have to make a special website for
robots
First try: harvesting of our existing
database – didn’t work
Extra database for harvesting
xml-format – Google ”standard” –
includes number of libraries per record –
names/links to libraries (we skipped
that).
The Google Scholar solution?




Only records already in Google
Scholar get library links
Google try to match their records
with our records
Their format does not have type of
material (book, article, video, etc.)
Number of libraries is used for
ranking (wasn’t in the beginning..).
The linking to bibliotek.dk




Google wanted choice of library as in
the links to Open WorldCat.
We only wanted a link from the record
in Google and the library choice to be
as usual in bibliotek.dk.
Compromise: when coming from Google
Scholar the user can see library
holdings, but choose library as usual.
Danish users (=IP-addresses) go to the
Danish version of bibliotek.dk.
Shortcomings - statistics



Type of material
Lack of users - usage: 0.1% of
bibliotek.dk visits (JuneSeptember) comes from Google
Scholar (total 1 mill. visits).
Lack of work display – FRBR - as in
bibliotek.dk
bibliotek.dk – FRBR
display all editions
Google Scholar –
highest ranked
edition
Google Books – no extra work for DBC



All bibliotek.dk-records of books are
used
Good tool for librarians all over the
world using only ”Library catalogs”?
Usage: 1.2% of visits (25. August24.September) comes from Google
Books (total 0.33 mill. visits).
Google links to bibliotek.dk




Many Danish web pages link to bibliotek.dk –
and these pages are indexed by Google
The Subject guide in bibliotek.dk is indexed
because it’s a webpage-hierarchy
We’ve optimized the urls of the Subject guide
– now all result pages are also indexed
Usage: 23% of visits (August-September)
comes from google.dk, -com, -de, -no, -se…
(total 0.33 mill. visits).
Is bibliotek.dk dispensable?




50% of our users go directly to bibliotek.dk
Many functions are only found here - libraries
can update informations every minute
Creating a website based on a bibliographic
database leads to other solutions than search
engines optimized for working with full text
documents
Knowledge of standards for bibliographic
data is a fairly good thing!
