The way to do this is to take the original PGN, and then _add_ to it with the stuff you want to use. In fact, the books.bin file is made to add to in this fashion, leaving book.bin to be a large "backup" for when books.bin is no longer useful. > >And my second ask: Is it the right way to produce own openings books with *your* >collections of PGN games on your ftp server?

It needs a lot more work, which will happen over the next year or two. I don't believe in hand-crafted books, as they require too much human labor. But they are difficult to beat, without a _lot_ of work...
