I signed up for my local library and bought a Kindle precisely so I can check ebooks. Come to find out there is a waiting list for every book I've found that it worth reading to me, some of the ebooks only having one "copy". I know the publishers license it so they can make money, but that's ridiculous. Limitations of physical goods should not translate 1:1 into the digital world. One physical book should be the same as 10 ebooks.
