How do I search HOLLIS with a numeric identifier such as an ISBN, DOI, PMID, or OCLC number?

Enter just the number (no spaces, no letters) into the search box.

HOLLIS’s main search box accepts common numeric identifiers such as ISBN, ISSN, DOI, PMID (PubMed ID), and OCLC numbers. It also accepts HOLLIS numbers, which are the unique identifier assigned to each Library Catalog record. 

Important notes:

  • Searching by ISBN, etc., is convenient but not exhaustive, as many HOLLIS records do not include the relevant numeric identifiers for the item.
  • Call numbers and barcodes are not searchable this way. 
    • To search by local call number, use Code:Local Call Number
    • To search by Library of Congress call number, use Starts with/Browse
    • To search by barcode, go to Advanced Search and select the “barcode” option next to Everything and Library Catalog
