Frequently Asked Questions

Get quick answers to common questions on collections, searching and more.


  • I’ve worked with a particular collection in the Ohio History Connection Archives/Library–why doesn’t it show up on Ohio Memory?
    • Digitization is a time-consuming and costly process, so we have only digitized a fraction of our collections. Materials are selected for inclusion based on their historical significance, scanning potential, complementary value, and ownership and copyright.
  • How are collections organized?
  • What is the Ohio Memory Collection on Ohio Memory?
    • Ohio Memory began in 2000 as a digital repository containing contributions from hundreds of cultural heritage institutions around the state. A lot of content has been added to the site since then, but most of the original contributions can be seen here, representing a variety of topics, time periods and institutions.


  • Why aren’t my search terms always highlighted on the images?
    • Materials uploaded as PDFs do not display highlighted terms the same way that materials uploaded as TIFFs do.
    • Your search terms must be exact matches for red highlights on images to appear. Partial matches may still show up in your search results and are displayed in the full-text transcript.
    • Handwritten materials often include transcriptions, but due to the nature of these materials, highlighting can only be displayed in the full-text transcript.
  • Where does Ohio Memory search for my term(s)?
    • Unless you limit your search term to a single field (i.e. Title, Place, etc.), matches are identified across all fields of an item’s metadata record, and full-text transcript, if available.
