;login: is a long-running bi-monthly technical journal published by the USENIX Association, focusing on the UNIX operating system and system administration in general. It was founded by Mel Ferentz in 1975 as UNIX News, changing its name to ;login: in 1977.[1]

;login: is published six times per year and is the #1 USENIX membership benefit. Single issues as well as subscriptions are available for purchase to non-members. Online issues of ;login: more than one year old are freely available for everyone to download, as are a number of articles in each issue. Currently, issues from 1997 through the present are available online.

The leading semicolon is a reference to the appearance of the login prompt of early versions of UNIX, where an escape code specific to the Teletype model 37 computer terminal would appear as a semicolon on other models of terminal.[2]
