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!
