This morning I drove up to the publisher's and turned in two full hard copies and a CD digital copy. Here's the stats:
70,000 words (I didn't count exactly)
325 pages, Courier New font, including notes and bibliography
123 sources in the bibliography
9-11th grade reading level
2 years of rather constant part-time effort (I think I went too slow, and didn't do anything at all in several different months).
They say it will be two months before I hear anything. I don't know what to do with myself now.
