Digital coding is the universal language allowing free translation between abstract information and physical books. Once upon a time, if you wanted the information, you had to physically possess (or borrow) the book. If you wanted to purchase a new copy of the book, the title had to be "in print."Link
This is no longer true. Scan the text once, digitally, and the information becomes permanently available, anywhere, no matter what happens to physical copies of the book. Search for an out-of-print title and you will now find bookshops (and libraries) who have copies available; soon enough the options will include bookshops offering to print a copy, just for you. Google Library and Google Print have been renamed Google Book Search – not because Google is shying away from building the Universal Library (with links to the Universal Bookstore) but because search comes first. To paraphrase Tolkien: "One ring to find them, one ring to bind them, one ring to rule them all."
Why does this strike such a nerve? Because so many of us (not only authors) love books. In their combination of mortal, physical embodiment with immortal, disembodied knowledge, books are the mirror of ourselves. Books are not mere physical objects. They have a life of their own. Wholesale scanning, we fear, will strip our books of their souls. Works that were sewn together by hand, one chapter at a time, should not be unbound page by page and distributed click by click. Talk about "snippets" makes authors flinch.
