The abbreviation cf. derives from the Latin verb conferre, to bring together (from which confer is the conjugation of the imperative form), while in English it is commonly read as \"compare\". The abbreviation advises readers to consult other material, usually for the purpose of drawing a contrast. Many usage guides recommend against the common use of cf. to mean \"see also.\" <\/p>\n
Such abbreviations appear most frequently in scholarly contexts, such as in academic articles in humanities, physics, chemistry, geology, open nomenclature biology, theology, philology,[1] or in economic[2][3] or legal writing.[4] <\/p>\n
The abbreviation cf. is used in essays,[5]theses,[6]technical books,[7]law review articles,[8]legal opinions,[9] and scientific nomenclature.[10] <\/p>\n
This abbreviation's general purpose is to compare the immediately preceding statement with another statement in the same work or, more commonly, a statement in another work.[6] For example, it might appear in legal writing like this: <\/p>\n
While cars are required by law to stop at all stop signs (Vehicle Code section 1234 [\"Cars must stop at stop signs\"]), pedestrians are not (cf. Vehicle Code section 4321 [\"Pedestrians need not stop at stop signs\"]). <\/p>\n
However, while the cf. abbreviation has widespread use as a shorthand for \"see\", particularly in citations, The Chicago Manual of Style recommends against its use in this sense and prefers instead that cf. be used only to mean \"compare\" or \"see, by way of comparison\".[11] <\/p>\n
In biological naming conventions, cf. is used in a few ways; commonly it is placed between the generic name and the specific name to describe a specimen that is difficult to identify because of practical difficulties, such as the specimen being poorly preserved. For example, Barbus cf. holotaenia implies that the specimen is believed to be Barbus holotaenia but the actual identification cannot be certain. <\/p>\n
The use of cf. in biological nomenclature expresses a possible identity, or at least a significant resemblance, such as between a newly observed specimen and a known species or taxon.[10] Such a usage might suggest a specimen's membership of the same genus or possibly of a shared higher taxon, such as in \"Diptera: Tabanidae, cf. Tabanus\" where the author is confident of the order Diptera and family Tabanidae, but can offer the genus Tabanus only as a suggestion, and has no information favouring a particular species.[12] <\/p>\n
The abbreviation only has a single period placed at the end (\"cf.\", not \"c.f.\") because cf. is a shortening of the single word, \"confer\", not a shortening of two words (cf. \"q.v.\" for \"quod vide\"). <\/p>\n
Use of italics for abbreviations of foreign words and phrases has become less common in modern usage, especially for such common abbreviations as cf., e.g., etc., i.e., q.v., and viz. <\/p>\n
