{{Other uses|Cf (disambiguation)}}{{wikt|confer}}

The abbreviation cf. (short for the {{lang-la|confer/conferatur}}, both meaning "compare")[1] is used in writing to refer the reader to other material to make a comparison with the topic being discussed. It is used to form a contrast, for example: "Abbott (2010) found supportive results in her memory experiment, unlike those of previous work (cf. Zeller & Williams, 2007)."[2] It is recommended that "cf." be used only to suggest a comparison, and the word "see" be used to point to a source of information.[3][4]

Biological use

In biological naming conventions, cf. is commonly placed between the genus name and the species name to describe a specimen that is difficult to identify because of practical difficulties, such as the specimen being poorly preserved. For example, "{{lang|la|Barbus}} cf. {{lang|la|holotaenia}}" indicates that the specimen is in the genus Barbus, and believed to be {{lang|la|Barbus holotaenia}} but the actual species-level identification cannot be certain.[5]

Cf. can also be used to express a possible identity, or at least a significant resemblance, such as between a newly observed specimen and a known species or taxon.[5] Such a usage might suggest a specimen's membership of the same genus or possibly of a shared higher taxon, such as in, "{{lang|la|Diptera: Tabanidae}}, cf. {{lang|la|Tabanus}}", where the author is confident of the order and family (Diptera: Tabanidae), but can only offer the genus (Tabanus) as a suggestion and has no information favouring a particular species.[6]
