Handbook
A handbook is sometimes referred to as a vademecum (Latin, “go with me”) or pocket reference that is intended to be carried at all times. It may also be referred to as an enchiridion.
Handbooks may deal with any topic, and are generally compendiums of information in a particular field or about a particular technique. They are designed to be easily consulted and provide quick answers in a certain area.
For example, the MLA Handbook for Writers of Research Papers is a reference for how to cite works in MLA style, among other things.
“Handbook” is sometimes applied to documents that are produced within an organization that are not designed for publication—such as a company handbook for HR, for instance. In this case, the term is used nearly synonymously with “manual.”
