18.1 General principles
Bibliography, specifically enumerative bibliography, is the discipline of citing reference matter in a consistent and accurate manner, so as to provide enough key material for readers to be able to identify the work and locate it in a library. Bibliographies occur in all types of publication, and are found in most non-fiction works (though depending on the type of publishing they may not be headed Bibliography—see 1.4.4).
The structure of bibliographic citations is determined by the referencing system in use in the publication concerned. In general publishing and academic publishing in the humanities, bibliographic citations are ordered (very broadly speaking):
Academic publishing in the sciences and social sciences uses author–date references in the text to source quotations and references to other authorities (see 17.3); this form requires bibliographic citations ordered:
A variation on the author–date system is the author–number system (see 17.4).
18.1.2 Placement within a publication
Citations are conventionally found in two different parts of an academic work:
• Note citations appear in footnotes and endnotes.
• Bibliography citations form a list of works that is usually placed at the end of a publication before an index.
In the interests of simplicity it is best to keep stylistic differences between note citations and bibliography citations to a minimum. The following distinctions are useful, however:
• Note citations will frequently require a specific volume and/or page number. Apart from page ranges to identify the start and end of chapters in books or articles in journals, bibliography citations will usually cite a work in its entirety.
• In bibliography citations, if an author or editor is cited before the title the surname should appear first, aiding the reader in navigating through a list. In note citations this is an irritant that reduces readability, and should be avoided:note citation

Except when it is necessary to clarify a difference between the two types of citations, examples in this chapter follow bibliography style.
18.1.3 Arrangement and ordering of a bibliography
A bibliography is normally ordered alphabetically by the surname of the main author or editor of the cited work. It is sometimes advantageous to subdivide longer lists, for example by subject or type of work. A typical division is that of primary and secondary sources; also, a separate list of manuscripts and documents may be made. A bibliography of primary sources is sometimes more historically interesting if ordered chronologically, or more practical if arranged by repository. For ordering in the author–date system see 18.5.
Alphabetization follows the same principles as in indexing (see Chapter 19); ignore all accents (index Müller as Muller, not Mueller) and treat Mc as Mac and St as Saint. see 6.1.8 for the indexing of names with prefixes.
Entries by the same author may be ordered alphabetically by title, ignoring definite and indefinite articles, or chronologically by year, the earliest first, and alphabetically within a single year. Alphabetical order is advisable when many works by one author are cited, but chronological order may be preferred if it is important to show the sequence of works. In second and subsequent works by the same author replace the name with an em rule or rules: Oxford style is to use a 2-em rule followed by a fixed thin space before the title or next element in the citation, with no punctuation after the rule:
—Tracing Missing Persons (Manchester, 1986).
More than one author
It is usual to alphabetize works by more than one author under the first author’s name. Names of authors common to subsequent works are replaced by as many em rules as there are authors’ names. Oxford style is to use 2-em rules for each name, as explained above, with a thin space after each rule and without punctuation.
When there is more than one citation of the same author, group references within these two categories:
• works written by a single author
• works written by the same author with any co-authors, in alphabetical order by surname of the co-author:Hornsby-Smith, Michael P., Roman Catholic Beliefs in England (Cambridge, 1991).
—Roman Catholics in England: Studies in Social Structure since the Second World War (Cambridge, 1987).

—and Lee, R. M., Roman Catholic Opinion (Guildford, 1979).

18.1.4 Bibliographic elements
As a general rule, it is important for citations in a bibliography to be consistent in the level of detail provided. Inconsistency is a form of error and will reduce the overall integrity of an academic publication. Moreover, readers should be able to infer reliably that an absence of information from one citation but not another reflects the bibliographic detail available from the texts being cited.
For published matter, the key elements required for a ‘complete’ citation are:
• person or persons responsible for the work
• title of the work or serial
• the edition being used, if not the first edition
• place and date of publication.
Some citations require further details: these will be covered in the various sections that follow. A decision to include other details (for example number of volumes, series title, or publisher) should be applied consistently to all citations.
For non-published material, such as manuscripts and electronic sources, there are fewer established conventions, and publishers are more open to whatever is provided, so long as the style is followed consistently and does not jar unnecessarily with the general pattern applied to published matter.
The means by which a reader distinguishes one element from the other is by its order within the citation, its typography, and its surrounding punctuation. It is therefore important to ensure that each part of the citation is presented correctly, and in the appropriate place.
All bibliographic information must be taken from the cited work itself, and not from a secondary source such as a library catalogue or other bibliography. Additional information not supplied by the work should generally appear within square brackets.
