For text page you will need a dedicated macro lens with a flat field. These are sharp edge to edge, as are many of the better standard macros......this is also DSLR territory as a standard lens with macro capability (as in a compact camera) is generally not capable of complete edge to edge sharpness. A copy stand will also help to ensure you text page is absolutely flat.

I endorse what John says...

However, there are some digital cameras that focus close at their longest zoom setting, as well as their shortest, and these generally have a flatter field when used long. My old Konica Minolta A2 is an example...

I was once required to photograph a credit card, and I used this camera, filling the frame. Even when printed one metre across, distortion was minimal, and sharpness excellent all over.....

The predecessor model to the A2, the DiMage 7, used the same lens and actually had a contrast-boosting scene mode called -TEXT- meant for copying documents, etc. (I used it once. It was OK.)

Unfortunately, I cannot think of any more recent models known to have lenses with the same attributes, but the most likely place to look would be amongst those cameras with lenses topping out at 150-200mm equivalent on the long end, and with a close focusing ability at that longest setting....

.... or you could admit defeat, get an entry level dSLR, and fit macro lens of your choice.
