A raw bitmap of a B&W 600DPI scanned book *page* will run about 1 MB--less for mmpb and more for trade and hardcover. Compressing the file can reduce the size by a factor of 10, scanning in grayscale will increase it. It is generally best to go light on the compression.
For OCR'ing I've found the 600dpi 16 gray multipage tiffs work best. Leaves me with a single file for the OCR software to process unattended.
