Over 430 new images have been added to The PERiodical Source Index (PERSI), the world’s largest and most widely used subject index for U.S. genealogy and local history literature. Over the past thirty years, the Allen County Public Library (ACPL) Genealogy Center has created more than 2.5 million searchable records in PERSI, indexing every article from more than 8,000 different periodicals. These include magazines, newsletters and journals, according to location, topic, surname, ethnicity and methodology. Most of PERSI’s articles are from periodicals covering the United States and Canada, but you can also find thousands of genealogy and local history entries (in both English and French) from Britain, Ireland and Australia.

The latest new additions were made to existing titles within the index. Additional years have been added to the American Genealogical Record, American Pioneer, Collections Historical and Archaeological Relating to Montgomeryshire and Its Borders, Missouri Historical Review, Nova Scotia Historical Society Collections, Now and Then, Oregon Historical Quarterly, Our Home: A Monthly Magazine, Tyler's Quarterly Historical and Genealogical Magazine, Ulster Journal of Archaeology and the Yorkshire Genealogist.
