Hi

Rather than have the hundreds of CrossRef member publishers depositing
book DOIs reply separately I've sent Chuck information about CrossRef
DOIs assigned for book and book chapters.  There are over 539,000
books in CrossRef. A summary of all the content in CrossRef and
monthly deposit numbers are here:

http://www.crossref.org/06members/53status.html

and the book information is here:

http://www.crossref.org/06members/51depositorB.html

(warning: the page takes a long time to load).

Regards,

Ed Pentz
