SEARCHING IN ASIA-RELATED DATA

A core task of Staatsbibliothek zu Berlin’s East Asia Department is to offer and continuously improve the conditions of a subject-specific, up-to-date, and comprehensive search for materials from and about Asia, as part of the CrossAsia portal. The different search options – bibliographic metadata search as well as the full-text search – will be further developed in line with the current requirements of the research community, and new techniques will be tested to support future research questions and methods.

METADATA SEARCH

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.

FULL-TEXT SEARCH

Since April 2018, CrossAsia provides a browser-based full-text search (Beta version), currently with about 120,000 titles, which is built from textual resources and objects hosted in the CrossAsia Integrated Textrepository (ITR). Its aim is to make licensed and free full-texts available for research and teaching, independently of database applications. The search is open to all users; authentication is required only if the respective database is accessed. In the future we plan to provide an API for more flexible and more experimental, explorative and analytical approaches as well as to provide visualisations of sets and parts of the full-texts hosted in the ITR. These developments are planned to enable researchers to directly work with the collections by using digital tools. Of course, all these services will guarantee compliance with the license conditions.
