The IRIS database contains over 500,000 bibliographic records for the 800,000 volumes of books, serials, and auction catalogs in the general and special collections, as well as descriptive records of approximately 3,000 archival and photograph collections. The database has the capacity to limit a search by date, language, format, and material type. Bibliographies and individual records can be printed, downloaded, or emailed.
Some records link to Web-based resources such as databases and finding aids.
Select IRIS with Auction Catalogs to search the entire Library catalog. If you prefer not to have auction catalogs listed in the search results, choose IRIS without Auction Catalogs . IRIS Auction Catalogs only provides the capability to search the Library's holdings of auction catalogs as a separate database. All IRIS search screens display context-specific help and examples. The Research Library provides two online resources that enhance the information available in some IRIS records.
