I really enjoy the ability to borrow ebooks from my local library, especially something that I will only want to read once. While I find this idea to limit the number of borrowers per license to be galling I also know that there will be very little direct impact to me. If something isn't available from the library I can just buy it. Not everyone is so lucky. Instead of contacting the publisher to voice my disgust I am going to contact my library to see how I can help.
I don't know if I can donate ebooks in general or specific ebooks, but I intend to find out.
