We both received Nook ereaders for Christmas & we love them. We were wondering where we can find ebooks to borrow instead of buying them.We spend much of the winter near Cottonwood, AZ & the public library has a program where winter visitors can get a library card for a refundable deposit of $10 which we use. But they do not have an unlimited supply of books available & much of what is in the catalog has only one copy available so there are long waits to get the more popular authors. We are fulltimers with Oregon residency but no property in Oregon. Most Oregon public libraries require residence in the city or county to get a card.Does anyone know of a state or local library that has a program like Cottonwood where we can get a card & download privileges?
