Electronic book file types

The file types you can choose from are:

compressed postscript
gzipped postscript
DVI file. Text and equations without figures. view with xdvi. Good for previewing.
Library of subroutine source code.

The books are blocked into files containing 50 pages. I am afraid 50 pages will still be too large for many printers. Some illustrations are so bulky that, unfortunately, some printers are unable to accept even a small number of pages. If you need to split up some files, I suggest ghostview.

As for Adobe's Portable Document Format (PDF), I am still waiting for someone to make a working converter for UNIX machines.
