Do You Know PERSI?



Do You Know PERSI?

No, not “Who’s PERSI?”, But “What is PERSI?”  PERSI, the Periodical Source Index, is your gateway to discovering amazing information about your family history. PERSI connects you to the material and journal records from the databases of over 8,000 genealogy and history societies from all over the world.  Allan County Public Library logo

2.7 million entries

PERSI enables you to easily locate key information about people and places. Containing over 2.7 million journal record entries from thousands of historical, genealogical and ethnic publications, it is a valuable family history resource. It can help to build the historical context around your personal research, and the world your ancestors lived in.

 What you can find in PERSI

Articles fall under twenty-two different subject headings, or record types. These include biography, cemeteries, census records, church records, court records, deeds, institutions, land records, maps, military records, naturalization records, obituaries, passenger lists, probate records, school records, tax records, vital records, voter records, and wills.

PERSI is crucial in identifying research, records and transcriptions that might not be found in any other print or online source. It also is key to locating “orphan” data – information relating to locations distinct from the periodicals they appear in. 

 Worldwide coverage

The majority of PERSI’s articles are from periodicals that cover the United States and Canada, but you can also find thousands of genealogy and local history entries (in both English and French) from the U.K., Ireland and Australia.

The Society’s journal, Families, has been indexed on PERSI, producing 1,566 entries. Using this index, members of Ontario Ancestors can then login to the Society website, go to “My Account”, click on Members Corner and then Families, to view the relevant issue.

Most Branches have past newsletters available on their websites for Branch members.
