In 1981, representatives of several major dialects began to pool their efforts to design Common Lisp, an `industrial strength' dialect of Lisp that would provide stability for commercial applications.

The initial design of Common Lisp was well received, and in 1986 X3J13 was formed to transform this work into a formal standard. The resulting design, X3.226-1994, is a standard for Common Lisp--not for the entire Lisp family.

The Common Lisp standard improves on earlier Common Lisp work by placing much greater emphasis on portability, clarifying many aspects of compilation semantics, and adding several major pieces of new functionality: an object-oriented programming system, a condition handling system, an improved iteration facility, and better support for large character sets.

As an official reference to the Common Lisp language, hardcopy documentation of ANSI Common Lisp, (American National Standard X3.226) from ANSI is always definitive.

The hypertext markup for this document was created by Kent Pitman, with the aid of a custom program written in ANSI Common Lisp and created specifically for this task. Funding for the markup task was provided by and copyright of the result is owned by LispWorks Ltd.

The Java applet used in the Symbol Index (visible only in some browsers) was written by Evan Williams. Its copyright is owned by LispWorks Ltd.

The HTML hypertext markup that implements the hypertext features of these World Wide Web pages of the Common Lisp specification, collectively the Common Lisp HyperSpec, is the property of LispWorks Ltd.

Distribution of the Common Lisp HyperSpec as a hypertext document on the Internet does not constitute consent to any use of the underlying hypertext markup for redistribution of any kind, commercial or otherwise, either via the Internet or using some other form of distribution, in hypertext or otherwise.

Permission to copy, distribute, display, and transmit the Common Lisp HyperSpec is granted provided that copies are not made or distributed or displayed or transmitted for direct commercial advantage, that notice is given that copying, distribution, display, and/or transmission is by permission of LispWorks Ltd., and that any copy made is COMPLETE and UNMODIFIED. IN PARTICULAR, the material that MUST appear in the copy includes:

1. this copyright notice and its date;
2. the main index page, ../Front/index.htm;
3. all HTML pages to which the main index page links using relative links;
4. all graphical (GIF) images to which it links using relative links, such as the LispWorks logo that appears on each page; and
5. all hypertext links, relative or absolute, such as the link to http://www.lispworks.com/ that appears on each page.

Permission to make partial copies is expressly NOT granted, EXCEPT that limited permission is granted to transmit and display a partial copy the Common Lisp HyperSpec for the ordinary purpose of direct viewing by a human being in the usual manner that hypertext browsers permit the viewing of such a complete document, provided that no recopying, redistribution, redisplay, or retransmission is made of any such partial copy.

Permission to make modified copies is expressly NOT granted.

Permission to add or replace any links or any graphical images to any of these pages is expressly NOT granted.

Permission to use any of the included graphical (GIF) images in any document other than the Common Lisp HyperSpec is expressly NOT granted.
