A tip on photographing documents:
Set the exposure in manual mode, not auto, using a grey card if you have one or if not using a typical page of the document and checking the result on the camera lcd by looking at the image and checking the histogram.
If you use auto exposure mode the exposure will vary with each page depending on the content and the camera exposure system can be confused by the combination of white background and page contents.
EDIT: I noticed in another thread that you intend to photograph images on a microfilm viewer. If this is the case, using the grey card to set exposure would not be applicable. Just use a typical document page to set the exposure on manual. Setting the aperture to f8 and adjusting the shutter speed to the correct exposure will be fine for your purposes. You will definitely need a tripod. For this application an inexpensive tripod will be fine (unless you plan to use it for longer range more distant subjects in the future, in which case investing more money would be justified).
You should also use manual focus as some documents may have no content where the focus targets are pointing. You can set up the tripod, autofocus on a document and then switch the focus to manual for the remainder of the shoot. Be sure the viewer is focused for each page.
