Most HathiTrust books must be "checked out" for one hour, due to licensing restrictions. If no one else is waiting to access the ebook, you can check it out again for another hour. The checkout period keeps renewing an hour at a time as long as you are actively viewing the book. 

If someone else is trying to access the book, it will go to them once the first patron's current hourlong checkout has expired. Therefore, if an ebook is currently unavailable, that means someone else is currently using it, and you will need to try again later to check it out.

The exception is older books that are in the public domain, which have no viewing restrictions.
