I think you're running into some digital rights issues. Publishers,
libraries and distributors, to name a few, can assign digital rights to
epublications that will limit the ability to transfer or copy or print
them. If this is the case, there's not much you can do. This happens
often with ebooks you purchase, but not always.
Open ADE on your computer and go into Library mode. Put your cursor on the
small arrow next to the name of one of the ebooks that's giving you fits on
your Lookbook. When you click on it, a small drop-down box will appear.
Click on 'Item Info' and a screen will display information about that
ebook. In the middle of that screen will be the digital rights assigned to
it. I'm not a betting man, but I'd expect to see that copying the ebook is
restricted.
Without debating the relative merits of whether an ebook should carry such
restrictions, it's the way that the Digital Millenium Copyright Act of 2000
has been implemented. And it's not just ADE. Bluefire Reader, Calibre and
Overdrive also manage digital rights the same way.
Hope this helps!
