Joe, as well as pages, I scan objects with depth for my records- Indian jewelry to moccasins- so use a scanner with lens- HP Scanjet 6300C.
I copy pages from books as well- the page doesn't have to be flat against the glass, so the spine isn't broken, it just sets on the glass (Of course valuable books are photographed instead). The bit of distortion doesn't matter with printed material.
I use jerry-built supports if the book is large- just happens that the scanner, supported on a low throw-away side table above the printer- an Epson stylus color printer good for photos- is the same height as my computer next to it. This usually holds the other half of those folio sized coffee table books.

I am lost on copy-paste, will have to try it with the programs I have. Most of my stuff is processed through the Adobe program that came with the printer so that I can adjust the stored image.

Question: A few sites don't let me (or I don't know how) save the image to disk (or give me something that I can't process with Adobe). I have photographed the flat computer screen instead, which yields a usable image of music sheets, etc. Any ideas on how to save these images directly without taking photos? There may be a format conversion I don't know about.
