ENQUIRE

Around 1980, approximately 10,000 people were working at CERN with different hardware, software and individual requirements. Much work was done by email and file exchange, which the scientists used to keep track of different parts of intersecting projects. Berners-Lee started to work for 6 months on 23 June 1980 at CERN, where he developed ENQUIRE as a personal organizational tool. The requirements for setting up a new system were compatibility with different networks, disk formats, data formats, and character encoding schemes, which made any attempt to transfer information between dissimilar systems, a daunting and generally impractical task. The different hypertext-systems before ENQUIRE were not passing these requirements i.e. Memex and NLS.{{Cite web|last=Berners-Lee|first=Tim|title=The World Wide Web: Past, Present and Future|url=http://www.w3.org/People/Berners-Lee/1996/ppf.htm|publisher=World Wide Web Consortium|accessdate=25 August 2010|authorlink=Tim Berners-Lee|date=August 1996}}

ENQUIRE had pages called cards and hyperlinks within the cards. The links had different meanings and about a dozen relationships which were displayed to the creator, things, documents and groups described by the card. The relationship between the links could be seen by everybody explaining what the need of the link was or what happened if a card was removed. Everybody was allowed to add new cards but they always needed an existing card.{{cite web|title=History of the Web |url=http://www.w3c.rl.ac.uk/primers/history/origins.htm |publisher=Oxford Brookes University |accessdate=20 November 2010 |year=2002 |url-status=dead |archiveurl=https://web.archive.org/web/20100925204436/http://www.w3c.rl.ac.uk/primers/history/origins.htm |archivedate=25 September 2010 }}

ENQUIRE was closer to a modern wiki than to a web site:

• database, though a closed system (all of the data could be taken as a workable whole)
• bidirectional hyperlinks (in Wikipedia and MediaWiki, this is approximated by the What links here feature). This bidirectionality allows ideas, notes, etc. to link to each other without the author being aware of this. In a way, they (or, at least, their relationships) get a life of their own.{{Cite web|last=Berners-Lee|first=Tim|title=A Brief History of the Web|url=http://www.w3.org/DesignIssues/TimBook-old/History.html|publisher=World Wide Web Consortium|accessdate=24 August 2010|authorlink=Tim Berners-Lee|date=c. 1993}}{{Cite web|title=A Little History of the World Wide Web|url=http://www.w3.org/History.html|publisher=World Wide Web Consortium|accessdate=25 July 2010|authorlink=Robert Cailliau|first=Robert|last=Cailliau|year=1995}}
• direct editing of the server (like wikis and CMS/blogs)
• ease of compositing, particularly when it comes to hyperlinking.

The World Wide Web was created to unify the different existing systems at CERN like ENQUIRE, the CERNDOC, VMS Notes and the USENET.

Berners-Lee came back to CERN in 1984 and intensively used his own system.{{Cite web|last=Berners-Lee|first=Tim|title=Information Management: A Proposal|url=http://www.w3.org/History/1989/proposal.html|publisher=World Wide Web Consortium|accessdate=25 August 2010|authorlink=Tim Berners-Lee|date=May 1990}} He realized that most of the time coordinating the project was to keep information up to date. He recognized that a system similar to ENQUIRE was needed, "but accessible to everybody." There was a need that people be able to create cards independently of others and to link to other cards without updating the linked card. This idea is the big difference and the cornerstone to the World Wide Web. Berners-Lee didn't make ENQUIRE suitable for other persons to use the system successfully, and in other CERN divisions there were similar situations to the division he was in. Another problem was that external links, for example to existing databases, weren't allowed, and that the system wasn't powerful enough to handle enough connections to the database.

Further development stopped because Berners-Lee gave the ENQUIRE disc to Robert Cailliau, who had been working under Brian Carpenter before he left CERN. Carpenter suspects that the disc was reused for other purposes since nobody was later available to do further work on ENQUIRE.

The application ran on terminal with plaintext 24x80.

The first version was able to hyperlink between files.

ENQUIRE was written in the Pascal programming language and implemented on a Norsk Data NORD-10 under SINTRAN III,{{Cite web|last1=Palmer|first1=Sean B.|title=Enquire Manual — In HyperText|url=http://infomesh.net/2001/enquire/manual/#editorial|accessdate=30 August 2010|authorlink2=Tim Berners-Lee|first2=Tim|last2=Berners-Lee|date=February–March 2001}} and version 2 was later ported to MS-DOS and to VAX/VMS.
