By adding information about the licence model on the Detail page
Improve usability by adding information on the Detail page for books purchased under a NL model that the options “Download PDF Chapter” and “Download PDF” in ToC does not work unless you first Download the book (check-out). As I was told when asking about it, this information is available in Libcentral. However, endusers does not have access to Libcentral. I would also suggest that you change “Download Book” on the Detail page to “Download Book (check-out)”. As a librarian I understand what check-out means and so does teachers and researchers, but necessarily not new students with low library skills. Think about it, you click on Download PDF in the ToC and a message pops up asking you to check-out the complete book, and no explanation offered. Not very user-friendly.
