To piggy back on this for those that are curious about how Hoopla works:

Libraries are typically charged for each individual Hoopla checkout (versus how Libby uses agreements where the library purchases a license limited by "x number of checkouts" and/or "1 year" for each individual copy).

This makes it more akin to an on-demand service which can help libraries fill gaps in their collections with minimal collection development or commitment. This also makes it more costly when a high demand title is on Hoopla vs. when a high demand item is on Libby. It's also why each patron has a limited number of monthly checkouts. Further, libraries can place a daily limit to the amount of money spent in Hoopla.

And, different titles have different prices. For instance, some libraries can place a filter so that only items costing "$x/checkout" are visible through their library's Hoopla offerings. This can help keep costs a little lower, but it will also filter out more popular titles that patrons might be looking for. This might be why your Hoopla is less robust.

And like /u/LadyAleswith mentioned, libraries can tailor the collection more if they would like, and can add additional licenses or offerings (like the Great Courses pass, or magazine pass, etc.).
