The location database of National Document Delivery System (ODR) and its new services

The ODR location database (http://odr.lib.klte.hu) provides location information on the holdings of five major university libraries of the century and that of other ODR members at least to the extent of document purchased from ODR funds for document delivery purposes. The interface of the database provides the possibility of initialising

direct interlibrary loan requests for the retrieved document at the selected location. The database at present contains 985.257 bibliographic records and 1.582.278 location data.

The size of the database requires slightly different search strategies from the ones used in an average size OPAC. Some new services of the database from offering options to sort the search results to adding a separate subject heading database to preco-ordinate the selection of subject terms to be used for retrieval in the bibliographic database makes the database more user-friendly.

The basic interlibrary loan service is enhanced with loan policy statements of libraries added, which can be checked just before sending out the requests without interfering with the already performed searches. Some new usage statistics are also available.
