Capstone Interactive allows unlimited circulation; other eBooks can circulate just like your hard copies with only one patron allowed to use them at a time and only for the specified check out time. For instance, OverDrive provides a service that essentially checks out eBooks and other electronic resources for a specified time and then forces them to expire on the device they have been downloaded at the specified termination time. Additionally, some eBook publishers require that libraries repurchase eBooks after a specified number of circulation. |
