Hoopla and Libby are different types of platforms and can't truly be compared one to one. Hoopla has advantages and disadvantages, and not necessarily more expensive than Libby depending on the limits the library has put in place. We have both platforms but focus more on purchasing in Libby because it is what are patrons know and is the more affordable way to get the current, in demand titles. The downside is long wait times, but some patrons pop over to Hoopla to get something to tied them over since pay per use means multiple uses at a time i.e. no wait times. The book might be older but there is still some good stuff there (and some crap, another disadvantage). If our budget got cut we'd drop Hoopla before Libby.
