  Also online is a draft of most of Paul Wilson's book-in-progress, <a href="ftp://ftp.cs.utexas.edu/pub/garbage/cs345/schintro-v11/schintro_toc.html"> (NEW!) An Introduction to Scheme and its Implementation </a> in html format for web browsing.  This contains most (but not all) of the material from the ASCII course notes on Scheme, in a much improved and expanded presentation.  (It's about 300 standard texinfo pages so far.  More material is in the works, including an intro to object systems and metaobjects.) Besides being a good general introduction to the Scheme  language, Scheme programming, and interpreters and compilers, it provides a general introduction to things like macros---making it good background reading for Stephen Carl's masters thesis. <p>
