@russellJan 24.2005 — #very old, but still pretty relavant, i'd reccomend [URL=http://www.amazon.com/exec/obidos/tg/detail/-/1566047579/qid=1106585064/sr=1-6/ref=sr_1_6/102-9896714-5058544?v=glance&s=books]The Official Netscape JavaScript1.2 Programmer's Reference[/URL]
Then, I'd reccomend either (or both of) [URL=http://www.amazon.com/exec/obidos/tg/detail/-/0764557831/qid=1106584861/sr=1-14/ref=sr_1_14/102-9896714-5058544?v=glance&s=books]Wrox Press Beginning PHP 5[/URL] and/or [URL=http://www.amazon.com/exec/obidos/ASIN/0764557076/qid=1106584911/sr=2-2/ref=pd_ka_b_2_2/102-9896714-5058544]Wrox Press Beggining ASP.Net[/URL]
A decent book on databases/sql is also essential.
Coupla notes -- some of the Netscape JS 1.2 stuff is obsolete, but it is a surprisingly good programming reference, and an excellent JS reference. Also, u can pick it up real cheap now.
Don't spend any money on a PHP 4 book. Go straight to PHP 5 if u are going that route. The differences are enormous. If you are interested in PHP then [URL=http://www.php.net/docs.php]PHP.net[/URL] is a website you should visit often.
I'd pick either PHP, ASP.Net or Java and focus on one of them until you are pretty good with it before spending much time or energy on the others. They are all worthwhile next steps for you. And of course, the links that MstrBob posted are essential (and free).
