For small works I prefer a scanner. It will pick up the detail much sharper than any camera that I have owned (and I own some good ones). My scanner is an epson perfection v30, but it is a few years old and I am sure there are newer versions of it. However with that said, I still edit in a photo program. I have photoshop, but Gimp is a good free program as an alternative that many use. I use it to get the contrast and colors just right!
Here is a comparison between a 'sharp' photo and the same work from my scanner. You can see how much finer the lines are from the scan and how it picks up all the minor variations that the camera lens missed.
