I had noticed that a lot of the books I had already read were on KU, but not many of the ones on my list to read were. That sort of makes sense because I read a number of series books (mostly trilogies) and KU seems to mostly cover older things but not more recent popular works. Unfortunately my reading list is now mostly up to recent popular stuff.
The library has a similar issue: they have the recent/popular stuff, but there's usually a waiting list for it. I reserved three books that had different wait times, the longest being two months out, but the shortest came up available the next day.
It works nice. When you get the book, you can read it on their web interface or app, but you also have them send it to your Kindle app, which is what I did. It shows up like an Amazon purchase, but with no cost, and then pops up in your Kindle library. You can have up to 30 books on hold (in your queue, waiting to be available) at a time, so depending on how fast you read, you can reserve a bunch so you're in line while you're reading others.
I think this will work good for me. It's all completely free, and I had spent over $200 on books in the last few months, so it's a giant savings of I keep this up. Thanks again.
College textbooks are a racket, for sure, especially when the teacher requires an expensive book that he or she wrote, which I had happen more than once. In one case, we didn't use that book a single time in class.
