The options for retrieving and displaying a patron's reading history are limited right now. In the staff client it fetches the whole data set, and in the OPAC it offers the option of either all or 50. I think a REST API endpoint would expand the options we could provide, including features like the one described in Bug 26570, "Search Functionality in Borrowing History."
