Your Visit to ACHS

Visitors are always welcome at the Adams County Historical Society and appointments are not necessary during our regular operating hours. Researchers will be asked to sign in and review our research policy, a copy of which is on our website. Society members can research free of charge, and non-members are asked for a $10 donation. We rely on these small donations and the work of our dedicated staff and volunteers to maintain the research rooms and assist the public in the best way that we can.

The Society has two main research rooms to serve the various needs of the public. If you are interested in genealogy, we have a large collection of church records, family files, and published or unpublished family histories. We also have access to every newspaper printed in Adams County, and an expansive index to marriage and death notices. Most of these newspapers are key-word searchable on our computers. In addition, the ACHS holds thousands of county records, including wills and estate papers, tax records, and other government documents that are useful to doing genealogical research.

Others who visit the society are interested in learning more about a house or other historic site in the county. For this type of research, we have the tax records of every township and borough in the county dating to its founding. We also have deed books and other property-related documents that are key to understanding the history of a house or farm.

Finally, the ACHS is known for its Battle of Gettysburg Research Room and Library where authors and Civil War enthusiasts can utilize rare collections of Gettysburg-related materials. The crown jewel of this room is our collection of hundreds of civilian accounts of the Battle of Gettysburg and Lincoln’s 1863 visit. This collection has been widely used by authors and students of the battle in books, papers, and other published materials.
