I frequently find books at Project Gutenberg which originally were printed with excellent illustrations but the files available contain only text. I often find scans of the printed (illustrated) versions at Books or Internet Archive and nowhere else. So the question is:
am I legally permitted to capture the images of the illustrations I want from those viewable scans (or downloadable PDFs) of public domain works and use them to create illustrated ebooks for posting here? I can't seem to find copyright information about the scanned images which, it seems to me, might themselves be protected. For example, a book I posted in text-only form is available in full-view here at Google:
http://books.google.com/books?id=rlQ...um=100#PPP1,M1
The only place I can see that might mention legal issues is here but I see nothing relevant to my question:

Ditto for this book that I posted for which the Internet Archive has a scanned copy:

Their Terms of Use document is here:

Any thoughts or experience with this?
