Actually, you don't have to go to umd website to download UMD e-books. There are too many advertisements. I hate them. Here, I will tell you how to search UMD e-books. I will search Baidu for "network disk search", which is a network disk search engine. When searching for UMD e-books, you can find many e-books by typing "title UMD". That's how I found the UMD e-book.
