Ray Rickman will host a "Value of the Book" workshop at Southworth Library on March 21, 6:30 p.m., where he will offer free book evaluations.

Rickman will draw on his many years of experience as a rare-book dealer, a former bookstore owner in Providence, and the former host of the Rhode Island Public Television program “Bestsellers.”

Rickman will discuss which sorts of books tend to have high market values, explain characteristics that can influence the worth of a particular book, and offer complimentary estimates of up to three books for each participant in an "Antiques Road Show" type format.

The event is sponsored by The Friends of Dartmouth Libraries and is free and open to the public.
