Abstract

This diploma thesis desribes a distributed library information system for bibliographic databases in the Internet. The name of the system is ZACK.

With ZACK the user is able to search for a particular document in several databases and to include the matches in his/her own local database. The inclusion of data records from an external database makes the capture of new documents much easier, as internal cataloging is reduced to a minimum. Double work is eliminated and a continuously high quality of data record is ensured.

The distributed search by means of ZACK is carried out in several databases in parallel. Duplicates are recognized; and a short list of matches without double entries is offered. The user can then decide for himself from which database to include data records. In practice, a distributed search has produced far better results than the search in one particular database. Response times are within an acceptable limit for the user. The short list of hits is made clearer and more concise by the duplicate check.
