I've been weeding the Rosemary Sutcliff on a book-by-book basis, but so far, none have survived but Black Ships Before Troy and The Wanderings of Odysseus. Her work, while extremely well researched, tends to be overly descriptive for my students. I've had a lot of interest in medieval times, and the Gerald Morris fans have been gamely trying things like Dawn Wind (which had not been off the shelf since 1980!) and The Capricorn Bracelet, but they are not happy. My daughter loves horses and will read everything, but even she did not get very far.
I wish I were an archive. *Sigh*
