For those PhD students interested in publishing their dissertations, Nijay Gupta is hosting some interviews (here) with those who have published their dissertations in various monograph series. For those who desire to publish but are clueless to the process, these interviews are a helpful starting place.
For a good book on scholarly publishing see Getting It Published: A Guide for Scholars and Anyone Else Serious about Serious Books, by William Germano. Published by The University of Chicago, second edition, 2008. This book is not only informative but a joy to read as well.
