Most home scanners, or printer-scanner-copiers are very slow when scanning.
Many libraries have book scanners that are much better: The scanners in two different local libraries are 3-5 times faster than my HP printer-scanner-copier, and they both scan right up to the edge, designed for the center binding of a book, so they avoid the shadow from the binding.
