Seems like whenever there's a nonfiction thread, there will invariably be posts by both triceratops and me. Here's mine.
Zepro, since I have been asked questions like yours before, I wrote up a whole FAQ about how my books, The Cincinnati Subway and Cincinnati on the Go came to be. Please see my
faq.
To answer your question in a nutshell:
I've been writing my whole life, and had been researching the business side of writing since the early 1990s. I got interested in the subject of the failed subway in Cincinnati in 1998, and when I looked for information on the subject, I couldn't find anything (nothing on the web about it at that point). Since I had always wanted to write a full-length book, I decided to write a complete history on the subject, try to attack it from every angle. And so I did.
Halfway into the project I started querying publishers: some university presses, some small nonfiction publishers. None were interested. I finished the book in 1998/1999 and put it aside when we bought our house in 2000. (Many other things were happening in my married life at the same time as this, btw.). In 2002 I found the publisher, as explained in the faq.
To answer one of your questions, when I DID locate the "right" publisher, I had my answer in less than a month that they were interested in publishing the subway book.
After signing the contract, with the editor's help, I had to reduce the amount of text in the book and revise and rewrite a lot of it. The end result was a much tighter, much better manuscript. I'm rather glad the original version of the manuscript didn't get published. Some text went to the captions (over 200 images in the book) and some got cut out entirely. Having the right publisher made it into a better book. You can "search inside" the book on
amazon.com for examples of how it came out.
I did not have an agent, and still don't, but I may try to seek one when I pursue other projects in the future--projects out of the scope of my present publisher.
I'm currently working on my third book for the publisher. It's true what they say, that when you get published the first time, the publisher wants you to write more for them since now you are a "commodity" who has proven to deliver a salable product.
I could go on and on. I should get back to work writing my book (oh, and I should also get back to working at my full-time job, too!)
PS, I have been very happy with my publisher, and other authors who have produced books for the publisher are happy with them too. I hasten to point out that it's not like Publish America's "10,000 happy authors." This publisher doesn't offer an advance (although I think they should), but the royalties have been very nice. Maybe not at the same level of James MacDonald, Victoria Strauss or AC Crispin, but for a first timer with a regional history book, I believe I've done pretty well.
