 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?
-
-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.

-The major Python Web site is \url{http://www.python.org/}; it contains
+real-world problems. Where should you go to learn more?

+users.

+\item \url{http://www.python.org}:  The major Python Web site.  It contains
 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. 
-Many more user-created Python modules
-can be found in the \ulink{Python Package
-Index}{http://www.python.org/pypi} (PyPI).
+
+\item \url{http://docs.python.org}:  Fast access to Python's 
+documentation.
+
+\item \url{http://cheeseshop.python.org}: 
+The Python Package Index, nicknamed the Cheese Shop, 
+is an index of user-created Python modules that are available for 
+download.  Once you begin releasing code, you can register it 
+here so that others can find it.
+
+\item \url{http://aspn.activestate.com/ASPN/Python/Cookbook/}: The
+Python Cookbook is a sizable collection of code examples, larger
+modules, and useful scripts.  Particularly notable contributions are
+collected in a book also titled \citetitle{Python Cookbook} (O'Reilly
+\& Associates, ISBN 0-596-00797-3.)
