Ulrich's Periodicals Directory (ISSN 0000-0175, and ISSN 0000-2100) is the standard library directory and database providing information about popular and academic magazines, scientific journals, newspapers and other serial publications.
The print version has been published since 1932, and was founded by Carolyn F. Ulrich, chief of the periodicals division of the New York Public Library as Periodicals Directory: A Classified Guide to a Selected List of Current Periodicals Foreign and Domestic.
Coverage is international, with some emphasis on English-language publications. The information is derived from the publishers and verified by the journal. It includes
- Title and previous titles
- Starting date, place of publication, and publisher
- Cost, availability of electronic versions, subscription terms, and approximate circulation as estimated by the publisher
- Subject information, searchable as subject terms or approximate Dewey Classification, special features, and indexing information
- Indications of whether the publication is available on open access
- Indication of whether the publication is peer-reviewed, which is taken to include professional magazines with equivalent editorial control of quality.
Earlier published by R.R. Bowker, it moved to CSA, a fellow subsidiary of Cambridge Information Group, in 2006. Following the merger of CSA and ProQuest, Ulrich's moved to ProQuest subsidiary Serials Solutions. The "Serials Solutions" name was retired in 2014
