'''SHARE Inc.''' is a volunteer-run [[Users' group|user group]] for [[IBM]] [[mainframe computer]]s that was founded in 1955 by [[Los Angeles]]-area users of the [[IBM 701704]] computer system. It evolved into a forum for exchanging technical information about [[programming language]]s, [[operating system]]s, [[database system]]s, and user experiences for enterprise users of small, medium, and large-scale [[IBM computer]]s such as [[System/360|IBM S/360]], [[System/370|IBM S/370]], [[zSeries]], [[pSeries]], and [[IBM System x|x]]Series.

==Overview==
A major resource of SHARE from the beginning was the SHARE library. Originally, IBM distributed what software it provided in source form<ref>{{cite web |url=http://www.princeton.edu/~melinda/25paper.pdf |archiveurlarchive-url=https://web.archive.org/web/20060513145315/http://www.princeton.edu/~melinda/25paper.pdf |archivedatearchive-date=May 13, 2006 |title=VM and the VM Community: Past, Present, and Future |first=Melinda |last=Varian |publisher=Princeton University |date=August 1997|page=54}}</ref><ref>{{cite web |url=http://www2.marist.edu/~vmshare/browse?fn=OCO:BDAY&ft=MEMO&args=KEYS#hit |archive-url=https://archive.today/20120630075636/http://www2.marist.edu/~vmshare/browse?fn=OCO:BDAY&ft=MEMO&args=KEYS%23hit |url-status=dead |archive-date=June 30, 2012 |title=MEMO OCO:BDAY - Today is OCO's tenth birthday |date=February 8, 1993 }}</ref><ref>

and [[systems programming|systems programmers]] commonly made small local additions or modifications and exchanged them with other users. The SHARE library and the process of distributed development it fostered was one of the major origins of [[Open-source software|open source]] software.<ref>{{cite web |url=http://www.soa-pipeline.com/news/169400167 |archiveurlarchive-url=https://web.archive.org/web/20060324140930/http://www.soa-pipeline.com/news/169400167 |archivedatearchive-date=March 24, 2006 |title=SHARE, IBM User Group, To Celebrate 50th Anniversary |first=David |last=Gardner |publisher=TechWeb News |date=August 17, 2005}}</ref>
 
In 1959 SHARE released the [[SHARE Operating System]] (SOS), originally for the [[IBM 709]] computer, later ported to the [[IBM 7090]]. SOS was one of the first instances of "[[commons-based peer production]]" now widely used in the development of [[free and open-source software]] such as [[Linux]] and the [[GNU project]]. In 1963 SHARE participated with IBM in the development of the [[PL/I]] programming language as part of the "3x3" groupcommittee.
 
In 1969, members of SHARE in Europe formed a European Chapter of the organisation, which was formalised in 1966 as the "Share European Association (SEAS)", later SHARE Europe (SEAS).<ref>{{cite web|url=https://www.daube.ch/share/seas01.html|title=30 Year History of SEAS / SHARE Europe|date=March 1992|first=Harry|last=Hurst}}</ref> The last meeting of 1994 was jointly held with G.U.I.D.E. At this meeting it was decided to dissolve both SHARE Europe and G.U.I.D.E. and establish the new European IBM users group GSE (Guide Share Europe).
 
SHARE later incorporated as a non-profit corporation based in [[Chicago, Illinois]] and {{as of | 2013 | lc = on}} is located at 330 N. Wabash Ave. The organization produces a newsletter and conducts two major educational meetings per year.
 
In September 1999, [[GUIDE International]], the other major IBM mainframe users group, ceased operation. Although SHARE did not formally take over GUIDE in the United States, many of the activities and projects that were undertaken under the aegis of GUIDE moved to SHARE, and GUIDE suggested to its members that they join SHARE. In August 2000, SHARE took over the guide.org domain name.
 
In 2005 SHARE's membership of 20,000 represented some 2,300 enterprise IBM customers.<ref>{{cite news |url=http://www.computerworld.com/hardwaretopics/hardware/mainframes/story/0,10801,100119,00.html |title=Share user group looks back at 50 years with buttons, ditties |publisher=Computerworld |first=Patrick |last=Thibodeau |date=March 2, 2005}}
