Hi. This is easy. To do it properly you need light. If you have a couple of flashes (not the flash of your camera) off-camera flashes and softboxes set one in the left and one in the right taking good care of the distances.
I think you don't have flashes. You need light again. Not direct sun, but open shadow (you can look for "open shadow in youtube). Use an easel for the pages so they can be set almost vertically. Basically, with the sun in front of you, look for a place in shadow who is near a white big wall or surface. This is going to be your reflector. if you have a tripod, use it, if not, be nice when shooting and make three photos of every page at least, just in case some got blurred. Put yourself in front of the page and at the correct angle. If you are looking through a viewfinder you can correct better, if you only have the little screen concentrate in the page looks straight and at the same distance and angles in the four sides.
The glass. I recommend shot this with a 90mm minimum. 120mm, 150mm. For an image with real proportions without distortions.
Now the settings. If you are shooting with a Full Frame camera, f-8 can do. If you have a crop sensor you can do at F-5.6 or less. The smaller the sensor the less f-number you can use. 5.6 is very good number in any case. The lenses work better in the middle of his range. In the extremes, you can have vignetting and other undesirables effects.
ISO Base of your camera, some have 100, some 200... Don't raise your ISO
And shutter speed, if you shoot with a tripod no problem. If you shoot without a tripod I recommend no less than 100 and the more the better. If you can get to 500 do it. If your camera has Image Stabilization technology you are safe at even 50 if you don't move. IS is a miracle! But even with stabilization speed don't hurt so the more the better.
Overexpose one stop, or perhaps more if you want the white, white. If you have histogram in your camera, let it to the right.
And finally, edit and retouch the final image to achieve the results you want. If you don't have the skills there's a lot of retouchers that work well online.
If all that is too much, the more important here:
Find light. You need light. Light is everything in photography. Use a Wall like a reflector on a sunny day if you don't have flashes.
And overexpose one stop, check in the screen that nothing is burned. In that case, correct 1/3 of step shoot and check again.
