I sort of inherited two photo albums with both paper CDVs and tintypes. I was able to very carefully cut two of the bottom corners of the paper that held in the photos with a razor blade such that I could remove them from the albums with tweezers without noticeably damaging the albums (hard to describe; have to see it). Then my wife - who is a good photographer and has high-quality equipment - took high-resolution photos of the photos and used processing software to clean up the images so as to remove scratches and the like that were on the originals. She was also able to adjust things like contrast to make them as sharp as possible. After all that we printed them on heavy stock on her printer which she uses to print her photos. I was then able to make copies of the images, reduce their file sizes, and email the copies to a cousin (she didn't need or want actual paper).
Taking a good photo is your best bet. Scanning can work but it could be almost impossible without removing the photos depending on where they are in the albums and the size of the albums. Also, the quality of your scanner is critical. My only scanner is my printer which is OK for many things but isn't good enough for quality prints or if you need to clean up the images (you want the highest-density image you can get for that to work well).
Taking a photo is also the best way generally to get prints of old slides too. You project them onto a good screen and photograph that.
