What do I do when ProQuest E-book Central says  Your session has expired, please refresh this page, search again or sign-in again..

• This means that E-book Central has detected the existence of a previous session that has timed out.

With ProQuest e-books, they will time out after 30 minutes of inactivity. So when you try to return to the e-book, it will give you that message. Usually, refreshing the page will bring it back.

If that doesn't work, try the following:

• Click on the Sign Out button in the upper right corner of the e-book and then use the URL you used to access the e-book to sign back in.
