When it comes to learning Flash, I’m a big fan of the Friends of ED books. My favourite is an oldie but a goodie, Flash MX Most Wanted Effects & Movies UK link US link, in particular the tutotial on SoFake.com (which is a lovely little website, with some great design feaures, in particular the use of sound is lovely).
Anyway, the publisher of the Friends of ED books, Apress, also make many other books about (less exciting ;)) computer things like PHP, Java, .NET, etc blah blah rhubarb. They’ve come up with a funky little Firefox extension that allows you to highlight a phrase on the web, right click and do an automatic search of their library for books related to that subject. I think it could be pretty handy when you’re looking to find info about programming and/or Flash. If you think so to then you can download it here: http://www.apress.com/misc/firefox/
