I was looking at the Cumulus Soaring website the other day and noticed some new publications, a hardcover book very similar to the Martin Simons series by Equip, all about the LS line of sailplanes, nicely done with lots of photos, color and black and white, the text is in German but there is an English supplement, I also ordered "On the Wings of an Albatross" by Jeff Byard, an in depth study of the Baby Albatross designed by Hawley Bowlus. Both are excellent and highly recommended for your soaring library.
