In perusing the H's, I note that there are two listings for the same author each containing one book. Both Stephen Hawking and Stephen W. Hawking both contain the book A Brief History of Time. This book was written by Stephen W. Hawking. If one copy is better then the other, the better copy should be put under the entry for Stephen W. Hawking and the Stephen Hawking entry should be removed. Sincerely Yours, Duane Iverson
