Periodicals Index Online (PIO) is the leading multidisciplinary index to the arts, humanities, and the social sciences. Over 6,000 journals are included, with around one million records from new journals added yearly. Complete runs of these titles are indexed, from first issue to 1995 or ceased date. Propylaeum Search includes a section of ca. 2.3 million records on relevant subjects to the year 2000. A national licence funded by the DFG grants access to that special subject section after registration by the Deutsches Forschungsnetz (DFN).
Stock: ca. 13 million records
State of Indexing: Search engine indexed by the Bavarian State Library
