Received permission from one prof emeritus, one current prof, and a layperson to have their names listed as contacts (to supply positive comments later that could be used for publicity purposes). This was what I needed to finish & send the 1st publisher proposal! Now I have to wait until I hear back from them, as they do not accept simultaneous submissions. Then I'll send out other proposals en masse.
Am almost finished with a 2nd proposal.
If this book is supposed to be published, I suspect it will happen, despite the economy, this being my 1st book, etc. I am doing all of the work I can to make an excellent manuscript and well-done proposals to the right publishers. The rest is up to the Spirit.
