I had a friend back in Oklahoma who liked to talk about Velikovsky, especially when Having Drink Taken. I couldn’t ever find Mr. V’s books in the library, though.
Well, they're in my library!
Most are also available used. Many suggest that Ages in Chaos should be read before Worlds in Collision, though the latter was published first. I believe that among the "many" was Albert Einstein. Einstein was rereading Worlds in Collision at the time of his death.
An interesting book about Velikovsky is Ginenthal's Sagen and Velikovsky.
