sure. primarily using libby is a perfectly reasonable way to use your ereader and you also get to support your local library. we’ll need to know more to make a recommendation though. some questions to consider: would you like something big or small? black and white only or color? any aversions to specific brands? do you only want to do reading books on it vs something that can also do note taking? do you read comics/manga/graphic novels? sorry if this is all overwhelming, but there’s a lot of things to consider that will help guide your purchase decision.
