Bill Sanders has done it again - and yes I know I am slow to blog it. Nevertheless his new book in PDF format, published by O'Reilly and titled Learning Flash Media Server 3, comes highly recommended.

On over 250 pages it covers a lot of ground to get you started with FMS3 and also quite deeply into more advanced topics. From installation to setup over SharedObject and streaming video and audio to server side programming, every reader will get something out of this book.

You can get more info on it at O'Reilly and also order it there for a mere USD $19.99.
