Review: This a comprehensive list of the earlier photographic patents. There is so much information within these pages. These patents have been meticulously researched by it's author, who is also a professor at a well known university. (She has also recently completed another book on American tintypes, published by the American Philosophical Society.) I don't understand why the first reviewer panned the book. It is what the title says it is, but maybe it wasn't what he expected.
Is the review positive or negative?
