OK, they're not really spooky; but it's Halloween, and the Free Library is debuting its first podcast series , currently featuring recordings of some memorable author events at the Central Library from the past few years--including Maureen Dowd's appearance in 2005; some people think she's kind of "scary "...--and soon to feature regularly updated podcasts of more recent author events. In the meantime, check out Free Library recordings of Khaled Hosseini , Richard Dawkins , Nikki Giovanni , Calvin Trillin , and more!
