Yes, book_1.00.pgn.gz is the book file from GNU Chess 5.02 cleaned up. Since the book changes less often than the code, it seems sensible not to make people download 26MB everytime, when 154KB will do! Also anyone who already has a database that exports relatively clean PGN, like the excellent free software tool SCID, can use their existing database of games instead. The difference between 26MB and 31MB is we removed duplicates from the book file using SCID, and deleted comments, and incomplete or corrupt games, and there were a lot of them. There is still plenty of "junk" in the book_1.00.pgn.gz file I believe. I'd be interest to hear from people who have tried loading up very large databases. Lukas put some work into making the 5.03 database binary format portable, and scalable, although on my machine the loading of the bundled book takes long enough.
