Archival Research Catalog (ARC)

New ARC Features

The Archival Research Catalog (ARC) has undergone a significant upgrade. ARC now has a new look and improved navigation tools. These improvements include:

Streamlined Basic Search Screen

  • ARC’s new Basic Search screen has been redesigned to emulate familiar search engines, like Google.
  • A basic search offers a keyword search box with options to search all archival descriptions, those with digital copies, or those related to particular people or organizations.

User Friendly Advanced Search Filters

  • Users can search for all keywords, search for exact phrases, find descriptions with at least one of the keywords, or find descriptions without the keywords. ARC users can search by Title only to reduce the number of irrelevant search results. Collapsible filter options provide a more streamlined view of search options and reduce scrolling.

Tabular Display

  • Archival descriptions are better organized with separate tabs for physical copy information, shot lists, digital copies, and hierarchy.
  • The tabular display reduces scrolling and makes it easier for users to pinpoint specific information in an archival description.

Graphical Hierarchy Display

  • Intuitive graphical icons illustrate a Record Group or Collection as a file cabinet, a Series as a drawer in that cabinet, a File Unit as a file folder, and an Item as a page from that folder.
