 As for outsourcing, books are often shipped to be scanned by low-cost sources to India or China.Alternatively, due to convenience, safety and technology improvement, many organizations choose to scan in-house by using either overhead scanners which are time-consuming, or digital camera-based scanning machines which are substantially faster and is a method employed by Internet Archive as well as Google.Traditional methods have included cutting off the book's spine and scanning the pages in a scanner with automatic page-feeding capability, with subsequent rebinding of the loose pages.
