The Staatsbibliothek zu Berlin developed a comprehensive subject-specific search engine for the CrossAsia portal by using the Pazpar2 technology. CrossAsia Search provides two complementary search areas: the first search area with more than 100 million bibliographical records allows searching for materials that are available via CrossAsia, either in print (e.g. via the direct interlibrary loan service “Blauen Leihverkehr”) or electronically via a link to the licensed electronic document. CrossAsia’s rights management guarantees direct and seamless access to the document. This search area will be continuously enhanced with relevant bibliographic records of providers and libraries (in different formats for bibliographic metadata and transmission interfaces), which will be automatically transferred to the order form of the Patron Driven Acquisition (PDA) or the DoD service respectively, if selected.
The second, extended search area includes in addition records of national and subject-specific international online catalogues and databases, e.g. the German union catalogues, COPAC with records of most of the British Asia collections, as well as catalogues of other relevant European and Asian libraries. It is not possible to guarantee direct access to the respective documents of the second search area; however, materials are searchable and can be proposed for acquisition via CrossAsia.
