why does my ebook only download for 24 hours when I need it for the whole semester
The default twenty four hour setting for eBook downloads is related to the number of access licenses attached to each eBook. This varies, and is determined by both publishers and the library. The library seeks to optimise student access to online content.
eBooks can be downloaded more than once if necessary. They can also often be read online, and selectively, without the need to download them at all.
