Other Ways to Access OHS Library Catalog Records
The Research Library contributes electronic catalog records to the Online Computer Library Center (OCLC) catalog, WorldCat. The database allows patrons to search for titles in numerous libraries at once. Many public and college libraries subscribe to WorldCat, which is also available online.
OCLC also provides an online catalog of archival materials, ArchiveGrid, which contains catalog records from libraries, archives, museums, and historical societies. (https://beta.worldcat.org/archivegrid/)
How to Search the OHS Collections Online Catalog
The Collections Online Catalog contains descriptions of most of the Research Library's books and serials and many of the library's manuscripts, photographs, maps, oral histories and other specially formatted items. The online catalog points researchers to items that they can request to view in person in the library; it is not a digital repository, although low resolution watermarked images are attached to some catalog entries.
The online collections catalog is located at http://librarycatalog.ohs.org/EOSWebOPAC/
The Catalog provides three search modes:
- Simple Search queries for the search term in every field of every record. It is the broadest search available.
- Browse Search produces a list of entries according to the index chosen (e.g. author, title, or subject). Search for authors in last name, first name order. Navigate through search returns page by page or by typing the beginning letter of your target.
- Power Search gives an array of options to narrow the search, including search multiple fields, search specific fields, use Boolean logic, land limit search by formats, media, language, location, or collection.
