Yes, but you would never find a highly sought out book that is available without a waiting list.

With physical books, this is possible since there is so much inconvenience involved in taking them out.

Moreover, in many cases, people don't actually search for books. They just go to the library and take a book that they find by chance.

When you have a situation in which everyone searches for ebooks all the time, it becomes very unlikely that you will find a good ebook that is available without a waiting list.
