Time-Life Books (especially Mysteries of the Unknown)

Does anyone know of an online reference for collectors of Time-Life books. I’m especially interested in the Mysteries of the Unknown series. I’d also be interested in the history of the imprint, and any non-online sources as well.

Thaks in advance.

Can’t say I know of such a reference but if one is found I would be interested in it myself. I have books from three different T/L collections(one, Foods of the World I have in it’s entirety) I find their history collections enjoyable too.
