+The System V Interface Definition is a series of publications describing the minimum required user and application interface expected of UNIX systems published as System V compatible.  Four known issues exist, published in 1985, 1986, 1992, and 1995, which cover System V Release 2.0, 3.0, 4.0, and 4.2 respectively.
+As the SVID was more particular to UNIX System V, it contains many components not found in the POSIX standard.
+From the introduction of the Fourth Edition:
+The System V Interface Definition (SVID) is intended for use by anyone who must understand the operating system components that are consistent across all System V environments.  As such, its primary audience is the application developer who is building C language application programs having source code that must be portable from one System V environment to another.  A system builder should also view these volumes as necessary tools for supporting a System V environment that will host such applications.
 ==== POSIX/IEEE 1003 ====

 The various interface facilities described herein are based on the 1984 /usr/group Standard derived and published by the /usr/group Standards Committee, Santa Clara, California.  The 1984 /usr/group Standard and subsequent work of the 1003.1 Working Group is largely based on UNIX Seventh Edition, UNIX System III, UNIX System V, 4.2BSD, and 4.3BSD documentation, but wherever possible, compatibility with other systems derived from the UNIX operating system, or systems compatible with that system, has been maintained.
+==== Spec 1170/Single UNIX Specification ====

+Spec 1170, now known as the Single UNIX Specification, is a standard maintained by The Open Group, consisting of the former X/Open and Open Software Foundation organizations.  This standard, which extends IEEE 1003/POSIX, is the primary standard administered by The Open Group today and the standard currently applied to systems wishing to utilize the UNIX trademark.
+Above is Go Solo, an informative work published by X/Open in 1995 with the initial version of the Single UNIX Specification included on a CD-ROM.  From the foreword:
+Go Solo is designed as an aid to understanding the Single UNIX Specification as well as a means of delivering 2,700 pages of X/Open Specifications in a convenient and easily accessible media, namely on CD-ROM with an SGML-based browser.
