There is a boost-user mailing list that might be helpful for asking specific questions but certainly read the provided documentation first. I wish there were better books on boost, myself, but as it stands its development cycle has a very fast turn-around and it would be challenging to stay current enough to author a book.
The only book I'm aware of on boost is "Beyond the Standard Template Library"
and it covers only a small subset of boost, and also a (now) quite outdated
version of it.
Yeah, that's the book I kept finding.
No particulars. I just want a general understanding so that I'll know when it would be a good idea to use it, so that I can then perform some in-depth analysis to see how exactly I could do so.
The stupidity of writing a book about boost is that boost is famous for being well updated. So it would be an antiquated and irrelevant book in no time. Where as the C++ standard hasn't been updated for a while (but I'm looking forward to the updates in 0x).
