International Collector's Library and Black's Readers Service

Every year my college's library holds a book sale. The past two years I've come away with some nice books. This year it was five Library of America volumes. Last year I snatched up a number of books published by the International Collector's Library, and Black's Readers Service, knowing nothing of either. They've been sitting in a box under my bed for a while now, and my curiosity has finally got the better of me. Can anyone tell me anything about either of these publishers? Are either still around and publishing? (I doubt Black's is, but the ICL might be) Are these books at all collectible? Any and all information is greatly appreciated.

ICL books are nice to read, if they haven't already fallen apart. They are very poorly made books, but popular w/ realtors/ interior designers for decorating. Check for closed auctions on ebay. Don't know about Black's Readers Service. Library of America = FANTASTIC!
