Forget about a complete book on Ajax, just download/install/use the libs
+ browse the source ..

http://jquery.com/docs/AJAXModule/
$("p").load("/test/ajax-test.html");

The author (John Resig) does have a book (Pro JavaScript Techniques)
coming out next month ...

So, I'd like to look into Ajax.

Any good books you can recommend? I know PHP pretty well, but I dont
have much experiance w/Javascript, or Java (but I know c pretty well).

I've only replaced a few actions (like rating items) with ajax calls
thus far.  I definitely like it and would like to put it in more, but
developing new functionality is taking a priority right now.  A
pagination system like the google method Mark mentioned would probably
help with database load and web admin productivity.  For example, it
would be great to send a search query via ajax to the database and get
all of the results to the browser.  Then javascript can hold the results
and display say 50 of them at a time in the html.  I feel that browser
memory issues could be a concern with this method if you have thousands
of results... maybe you still need to have a limit on the query.  Anyone
run into browser memory issues with ajax?

I'm also not exactly sure of the best way to deal with the browser back
button and location bar issues with bookmarking.  I'd be interested to
hear what people on this list have found as the best way to do that.

Also... are people using a javascript framework for the ajax
functionality?  I've tried out prototype and jquery.  I like both of
them, although jquery is much smaller and I've been using that over
prototype since it seems to provide everything I need.
