Libraries have policies that outline proper usage of reference materials as well as the function of the reference staff. Reference materials are usually only available for use at the library and include dictionaries and encyclopedias. Usage of rare or delicate materials may require the supervision of a library staff member.
Reference policies outline what services are provided, who has access to reference services and the depth of assistance provided by the library. Reference policies set by libraries associated with the American Library Association must follow the ALA Code of Ethics.
Effective reference policies ensure that users make the most of library resources. Reference policies in libraries that provide access to rare and delicate texts allow members access to difficult-to-find material while ensuring preservation for future generations.
