About the Bibliography of Asian Studies from their website, http://bmc.lib.umich.edu/bas/Help/about .
This on-line version of the Bibliography of Asian Studies (BAS) contains 787,165 records on all subjects (especially in the humanities and the social sciences) pertaining to East, Southeast, and South Asia published worldwide from 1971 to the present. In 2011 the interface of the BAS was completely rebuilt and now uses an up-to-date search engine and facets, while all the entries were converted into Unicode format.
The BAS is updated regularly, with batch posting of thousands of new entries in each upload.
In addition to entries compiled since 1997, the online BAS includes the full data of all of the printed volumes of the BAS issued from the 1971 up to the 1991 volumes (published in 1997). The most important 100+ periodicals in Asian Studies as identified by the BAS staff are indexed as immediately as possible, but the total number of indexed journals is many times that amount; full information about the years of coverage of each and every journal is provided through the Journal Title Browse function. In addition, various special projects have contributed substantial numbers of additional records to the database (among them journals on Southeast Asia dating as far back as 1779).
Through the 1991 printed volume, the BAS included citations to Western-language periodical articles, monographs, chapters in edited volumes, conference proceedings, anthologies, and Festschriften, etc. Monographs published since 1992, however, have not been added to the database, and users seeking such monographs are urged to consult other general resources and databases such as WorldCat.
