 Reading this tutorial has probably reinforced your interest in using
 Python --- you should be eager to apply Python to solving your
-real-world problems.  Now what should you do?
+real-world problems. Where should you go to learn more?
 
-You should read, or at least page through, the
-\citetitle[../lib/lib.html]{Python Library Reference},
-which gives complete (though terse) reference material about types,
-functions, and modules that can save you a lot of time when writing
-Python programs.  The standard Python distribution includes a
-\emph{lot} of additional code.  There are modules to read
-\UNIX{} mailboxes, retrieve documents via HTTP, generate random
-numbers, parse command-line options, write CGI programs, compress
-data, and a lot more; skimming through the Library Reference will give
-you an idea of what's available.

 code, documentation, and pointers to Python-related pages around the
 Web.  This Web site is mirrored in various places around the
 world, such as Europe, Japan, and Australia; a mirror may be faster
 than the main site, depending on your geographical location.
