Book scanning
Book scanning or book digitization (also: magazine scanning or magazine digitization) is the process of converting physical books and magazines into digital media such as images, electronic text, or electronic books (e-books) by using an image scanner. Large scale book scanning projects have made many books available online. Digital books can be easily distributed, reproduced, and read on-screen. Image scanners may be manual or automated. After scanning, software adjusts the document images by lining it up, cropping it, picture-editing it, and converting it to text and final e-book form. Scanning resolution for book digitization varies depending on the purpose and nature of the material. High-end scanners capable of thousands of pages per hour can cost thousands of dollars. Projects like Project Gutenberg, Million Book Project, Google Books, and the Open Content Alliance scan books on a large scale. Image scanners may be manual or automated.
