Definition of Types of Reference Books
abstract
A brief, objective summary of the essential content of a book, article, or other
work, presenting the main points in the same order as the original but with no
independent literary value. An abstract can be indicative, informative, critical, or
written from a particular point of view (slanted). In a scholarly journal article, the
abstract follows the title and the name(s) of the author(s) and precedes the text.
almanac
An annual compendium of practical dates, facts, and statistics, current and/or
retrospective, often arranged in tables to facilitate comparison. Almanacs can be
general (example: World Almanac and Book of Facts) or related to a specific
subject or academic discipline (Almanac of American Politics).
bibliography
A systematic list or enumeration of written works by a specific author or on a
given subject, or that share one or more common characteristics (language, form,
period, place of publication, etc.). When a bibliography is about a person, the
subject is the bibliographee. A bibliography may be comprehensive or selective.
Long bibliographies may be published serially or in book form. The person
responsible for compiling a bibliography is the bibliographer.
dictionary
A single-volume or multivolume reference work containing brief explanatory
entries for terms and topics related to a specific subject or field of inquiry, usually
arranged alphabetically (example: Dictionary of Neuropsychology). The entries in
a dictionary are usually shorter than those contained in an encyclopedia on the
same subject, but the word "dictionary" is often used in the titles of works that
should more appropriately be called encyclopedias (example: Dictionary of the
Middle Ages in 13 volumes).
directory
A list of people, companies, institutions, organizations, etc., in alphabetical or
classified order, providing contact information (names, addresses, phone/fax
numbers, etc.) and other pertinent details (affiliations, conferences, publications,
membership, etc.) in brief format, often published serially (example: American
Library Directory). In most libraries, current directories are shelved in ready
reference or in the reference stacks.
encyclopedia
A book or numbered set of books containing authoritative summary information
about a variety of topics in the form of short essays, usually arranged
alphabetically by headword or classified in some manner. An entry may be signed
or unsigned, with or without illustration or a list of references for further reading.
Headwords and text are usually revised periodically for publication in a new
edition. In a multivolume encyclopedia, any indexes are usually located at the end
of the last volume. Encyclopedias may be general (example: Encyclopedia
Americana) or specialized, usually by subject (Encyclopedia of Bad Taste) or
discipline (Encyclopedia of Social Work).
handbook
A single-volume reference book of compact size that provides concise factual
