What about a modern islamics collection to complement the 2 excellent CP collections? e.g. Parshall, Glaser, Musk, Montgomery Watt, Schenk , Miriam Adeney, Vivienne Stacy, Wickwire. I have their books, but would happily pay again to get them on ereader. Actually Vivienne Stacy's books can be downloaded free from st. Francis magazine, which has lots of other excellent resources.
