Anyone who has bought a textbook, whether it be during college or graduate school, understand how expensive these costs can be. College textbook rental startup BookRenter is hoping to make the process of buying textbooks more affordable by offering an online site to loan books to students for a fixed duration. Today, the startup is opening up its platform to other sites to allow any college or business to launch its own online textbook rental store. Partners, such as universities or campus bookstores, will be able to use BookRenter's API to set up a virtual store on their sites. Partners have access to the same selection of textbooks available on BookRenter's site (which are electronically sourced from the largest textbook supplier)s. Partners can also use BookRenter’s dynamic pricing engine, which updates textbook prices in real time by responding to shifts in market supply and demand, as well as its customer service support. And BookRenter offers partners analytics platform and on-demand reporting capabilities, to give them intelligence on what's selling.
