How do I access an eBook that says "Preview"?

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, you will have to fill a small amount of information, but then the title becomes permanent, and the next time you access it there will be the option to "Read Online" or "Download" instead of "Preview".
