Union Catalog Record Types

When in doubt, do not specify a record type in your search. Each library uses different record types, and some record types overlap – for example, some libraries may label auction catalog records as books. See below for tips on using record types to narrow your search.

If you are interested in searching only journal articles, enter “article” in the record type box and select “All Libraries and Indexes” from the drop-down box.

To find information about a journal, including the library’s holdings, enter “journal” in the record type box.

To find books and catalogs, enter “book”.

The following record types are used in the catalog:
The libraries that use each type are listed in parentheses. For more information about the collections of libraries in the union catalog, see About the Philatelic Union Catalog.
