Database files for chess books

Having recently flipped through all 7 of Kasparov's recent books (5 volumes of My Great Predecessors, Revolution in the 70s and the latest Kasparov-Karpov 1975- 1985), I want to have the games in a computer database. What a common nerdy desire! Books are great for calmly re-playing through the moves, but what if I want to add a variation refuting Kasparov's analysis (notes on the margin?), or reference a game from the book in my own analyzed game? I also want to have a collection of games that are useful for understanding the middlegames arising from the openings that I play, and Kasparov's books are good for learning about historic development of plans and ideas (but only some games are relevant to my repertoire).

Seems like I already paid for the contents of the books, I would not be violating anything by having them on my computer (especially - if they are without annotations). A while back gambitchess.com started a great collection of database files for published books, but they don't have Kasparov's books. Yet looking around the Internet, I can only find 2nd and 4th volume of My Great Predecessors in pgn/chessbase formats. Chessgames.com has the collections of games that I need, but I can't download them in one shot without becoming a paid member. Seems like I might just have to download them one by one ...
