Publications are provided as 'perfect-bound' books, velo-bound copies, and/or on CD-ROM.

CD-ROMs are compatible with most operating systems (Windows, MacOS, SunOS, Linux).  Files are provided in Postscript and PDF format, and software for viewing these file types is included on the CDs.

Velo-binding consists of two plastic strips held together by glue. These strips are placed along the left edge of the document, as in this picture.
