OACIS is a freely accessible, continuously updated union list of
journals and serials on or about the Middle East, including those available in print, microform, and online.
The term "union list" as used by libraries is a unified listing of materials held
distinctly or in common by a group of libraries.
When selecting titles for our union catalog, we referred to the
African & Middle Eastern Reading Room
in the Library of Congress.
In particular, we use their list of
Countries, Areas, and Languages
Covered by the Near East Section when extracting bibliographic records from our members' catalogs.
