Query: Things you can tell just by skimming through it

This book is very informative and full of eye-opening photographs. It reflects an issue that needs to be addressed much, much more. I already knew much about this silent star, and have learned more just by simply skimming through Mr. Mann's excellent survey. I definitely recommend it as I also recommend another of the author's books, which I am currently reading as well, "Behind the Screen: How Gays and Lesbians Shaped Hollywood 1910-1969."
