site map


This site is devoted to the needs of the existing and potential Lisp community:
  • Lisp users can use this site as a starting point to locate:
    • Information about Lisp.
    • Applications and code that uses Lisp, or is in support of Lisp.
    • Contacts with other members of the Lisp community.
  • Programmers, other computer professionals, and their managers can use this site to help them determine whether Lisp is appropriate for them.
  • Vendors, educators and others can use this site to publicize their work.
The emphasis of this site is on real-world, industrial applications, and so most of the site refers to Common Lisp, though references are also made to other languages. In particular, in the interest of clarity, much relevent work in Scheme has been deliberately omitted. The "Related Languages" page gives starting points for information about Scheme and ISLisp.

The Association of Lisp Users

The Association of Lisp Users (ALU) is a user group which aims to promote Lisp, help inform and educate Lisp users in general, and help represent Lisp users as a group to the vendors. The ALU holds an annual conference and supports the formation of inter-vendor standards. ALU has international membership and is incorporated in the US.

If you have general questions about Lisp, please see the newsgroups and mailing list pages of this site.

What's New at This Site

This entire site is new. It's development began in the summer of 1996. Small changes are logged.

In July, 1998, a page on "Computational Resources and Efficiency in Lisp" was added to the What is Lisp? area.

The previous home page of the ALU was


The hierarchy is divided into nine groups: Each of these groups is listed on the contents page, and navigation bar displayed at the side or top of each page. In color-capable browsers, each group has its own color. The other pages available within a group are listed at the bottom of the navigation bar.

The navigation bar also has the ALU logo, contents. Clicking on this logo brings you back to the contents page.

The Site Map lists each file that is maintained as part of this website. The files are listed by group.

Repeatedly clicking on next will take you on a "guided tour" moving through each page in the site. prev goes back to the previous page or grouping, while up moves up within a grouping back towards the contents page.

Any appearance within a different host hierarchy does not imply any connection with, or endorsement by, the Association of Lisp Users.

A gnu compressed tar file containing a snapshot of the current contents of the entire site is available for download from the file ../admin/alu.tgz. There is a log of changes for different versions of the .tgz file. If you make a mirror of this site (perhaps in a language other than English,) please let us know so that we can put a pointer to it on the initial welcome page. Also, any publicly available or commerically used mirrors should be complete and unedited copies, except that faithful translations to languages other than English are acceptable and encouraged.
