Opening VLeBooks PDA titles
When viewing an eBook on the VLeBooks platform sometimes you will see the following screen, where the most obvious button says "Preview":

If you select Preview you will be able to access the full eBook. After 5 minutes a pop-up will appear asking if you want to continue accessing this resource. If you say yes, it will ask for a Library Card Number, which is your standard username (e.g. c1234567 for students). If you are a member of staff, please enter your computer ID, staff email address, or full name to access the resource.

After that the title becomes permanent, and the next time you access it there will be the option to Read Online or Download instead of Preview.
