Be aware that digital books purchased by Moody Library come with licenses, which equates to checking out a book. In most cases, the library has one license per book although there can be exceptions. If we have one license, then only one person can use the book at a time. Some digital book will have three licenses, which is the most any will have. If you find a book from the EBSCO or ProQuest Ebook collections, they will have four licenses. If you cannot get access to a book, then you will have to wait to use it or find something else that is available.
