As you have probably guessed, there are many sources of information about Linux available apart from this book. In particular, there are a number of books, not specific to Linux but rather about UNIX in general, that will be of importance, especially to those readers without previous UNIX experience.

Specifically, the book Learning the UNIX Operating System, by Grace Todino and John Strang, is a good place to start.

If you do not have online access to any of this material, you might be able to find someone kind enough to give you hardcopies of the documents in question. Read on.
