You present the facts as you interpret them in your own >particular style. It's your work. DHM I'd be interested in the legal situation. It is interesting for me, but it probably takes an expert on these issues. To some extent I can see that it doesn't seem to be much of an issue in real life as human opening books ( both the internal ones of players and those published as new sources) suffer from the very same problem. In "real" books, usually sources are given ( though not always) , so it might be more like a scientific work. I remember I checked one past Fritz opening book and it contained the complete NCO ( conclusion from a still very limitted sample) amongst other lines. There is some creative work involved either way( btw, in the simple ( simplified) examples I gave myself not really much IMHO), by selection of sources and additional analysis and verification ( discarding and adding lines) , but opening books clearly depend heavily on work done by others. For Crafty and the last two WCCCs I think IM Larry Kaufman should be called a Crafty team member when it is about book, as I more or less adapted the basic design of an opening repertoire published by him, including quite a lot of independent analysis done by him. If the opening book were treated just like an engine it would be called a clone I assume :) . It is no issue as it wasn't published, but I would feel strange about calling myself the author. The 2006 book will be different and most probably stand on the shoulders of a wider variety of sources and more personal choices , but again I wouldn't feel comfortable about publishing due to copyright issues .
