Customer Support Ruling

   
 

Libraries
Updated January 2001

PS-022 (483)

This Customer Support Ruling provides a definition of “libraries” as stated in the Domestic Mail Manual.

The libraries referred to in Domestic Mail Manual (DMM) 483.2* are public libraries.  A public library typically is one which is supported by public funds and whose services are freely available to everyone.  The libraries mentioned in those regulations may also be school, college, or university libraries when the reference materials are available to the public even though on site reference is required.

*See also DMM 183.3 and 383.2.
