I view wish list and to be read list as different list. To be read is the list of books that I have purchased and are in my to be read list (a book a day, and I should be able to knock it out in a year or so
). Wish list is books that I want to buy but haven't found them in ebook format yet. For the most part, this tends to be semi-obscure (at least now) authors whose books I have in paper and enjoyed, or history books written before ebooks (or computers for that matter).
