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 (June-September) 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. August- 24.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!
