Survey designs and statistical methods for the estimation of avian population trends

Founded in 1971 by Wayne Somers, a former college library bibliographer, Hammer Mountain Book Halls began as a catalogue business specializing in out-of-print scholarly books. We chose the name for euphony and because we occupied the second-highest point in the county, the top of a 1,200 foot hill. Since 1981, we've also operated "W. Somers, Bookseller," a retail book shop with a constantly changing general stock of books not listed on the Internet. It's open Monday-Friday, 11-5, and Saturday, 10-5; browsers are welcome. We've been members of the Antiquarian Booksellers Association of American since 1977. We're also the publisher and sole source of the invaluable "Bibliography Finder for American Authors," by Wayne Somers and Ilse Pinkus, which you can buy for a pittance through Advanced Book Exchange.
