More About the Periodical Source Index

The Periodical Source Index, or PERSI, is the largest and most widely-used index of genealogical and historical periodical articles in the world. (As used here, periodicals are defined as simply publications produced regularly as part of a series. They include such publications as magazines, newsletters, journals, etc.) There is an amazing amount of genealogical information and knowledge that is published in these periodicals every year. Created by the Allen County Public Library in Fort Wayne, Indiana, PERSI is widely recognized as essential for high-quality genealogy research.

PERSI is a comprehensive subject index to genealogy and local history periodicals written in English and French (Canada) since 1800. The collection also includes literature dating from the 1700s, although the material before 1800 is less complete. In printed form, PERSI spans over two dozen volumes and takes up several feet of shelf space.

Last year, the Allen County Public Library added more than 100,000 citations, bringing the total number of fully searchable records to more than 1.1 million. The index catalogs almost 5,000 different periodicals, listing every article according to locality, family (surname), and/or research method. PERSI is available on CD-ROM and to Ancestry.com subscribers.
