MHS Collections Available Online

The MHS provides digital access to our collections in a variety of ways through thematic resources, digital publication projects, digital content linked to collection guides, digitized public domain materials, and subscription databases. We will be updating this section regularly as we work to make resources available during the MHS closure period.

ABIGAIL Catalog Records with Digital Content

Many catalog records for single items contain links to digital versions of those items. A search in our online catalog ABIGAIL for the phrase "Click here to view this item" in quotation marks using the Keyword Anywhere search option will return over 950 items that have digital versions linked to their catalog entries.

Collection Guides with Digital Content

In recent years, the MHS has piloted full or partial digitization of manuscript and visual material collections using the online collection guides as a delivery system. Look for the blue digital content indicator next to the collection guide link and/or collection guide subsection as you browse in order to locate digital facsimiles.
