I've mentioned some titles by published by Packt in the past.
What makes Packt different is their philosophy:
Packt believes in Open Source. When we sell a book written on an Open Source project, we pay a royalty directly to that project. As a result of purchasing one of our Open Source books, Packt will have given some of the money received to the Open Source project.I don't know how that works out in reality, but the idea is good. In any case they have some very interesting titles coming up over the next few months: Implementing Sugar CRM - the book I needed last year! Building Forums with VBulletin - although they don't say which versions this covers it could be a useful read. Building Websites with Joomla! - Joomla forked from Mambo Open Source and has become very popular with developers. I'm currently experimenting with it on a couple of sites, as some of the plugins / components may help with non-technical users Building Responsive Web Applications with AJAX and PHP - they could just as easily have called this web 2.0 with php.. It seems to be the "hot" topic
