Access to documents: It might seem you can access a book that isn't on your ebrary site...

There are three cases you might experience with respect to trying to access a book that is not on your ebrary site:Case I. If you go to your ebrary site (signed in or not, it doesn't matter) and search for a title not on your ebrary site...

You'll find no results - the book isn't on your site

Case II. If you go to your ebrary site, make sure you are signed out (that is, you are not signed in to your personal ebrary account) and use a direct URL to a book not on your ebrary site (perhaps it used to be)...

You will receive a document-not-found error

Case III. If you go to your ebrary site, sign in to your personal ebrary account, and use a direct URL to a book not on your ebrary site (perhaps it used to be)...

It will seem as if you have full access to the document; however, if you click on the live TOC somewhere in the middle (to make sure you are in the content, not the front or back matter), then try to turn a few pages, you will be notified that you are seeing a "preview only" copy of the document

If the title is not on your site, "Preview Title" will be displayed in the toolbar:

To summarize, the surprising case is this:  if you're signed in to your personal ebrary account and you use a direct link to a book, you'll be shown a "preview only" copy of the book if it isn't on your site - and you may not recognize right away that it is a preview-only copy.
