The folks over at hardcore collector's haunt Digital Press have announced the free PDF and $28.99 fully printed version of Kevin Bryan's book 'PSX: The Guide to the Sony PlayStation'.

As the book's intro explains, the book "...provides the ultimate collector resource for fans of the system. A 60-page rarity guide, based on three years of price tracking and the input of the top Sony collectors in the world, lets the user find exactly the information they need to complete their own top-shelf collection".

There's also a bunch more pages of features, rare game spotlights, and other neatness, and you have to set up a Lulu.com account to download the PDF, but it seems eminently worth it if you want to know about Little Big Adventure or the Capcom Generations set for PSX. [Via Joystiq.]
