Books provide basic introductions to the theory and process of administering libraries and other information agencies, reference tools for finding statistics and other factual background, and in-depth treatment of special topics.

Reports and other forms of grey literature are sources for the latest thinking, proposed changes to regulations and practices, training materials, and so on.

Some grey literature is published in print format and may be acquired by the library. Use the online catalog to find it.

More and more gray literature is published solely on the web, usually in HTML or PDF formats. To find it, use a web search tool such as Google. 

Gray literature is also found in digital repositories, such as E-LIS.
