Do you remember the days when a librarian checked out a book by removing a paper card from a pocket in the back of the book, writing your name on it, and then marking the due date with a satisfying thump of an ink stamp? Many of you probably do not: the advent of the barcode has made such methods obsolete in all but the tiniest, most technology-free libraries.
N. Joseph Woodland, who pioneered the concept of the universal label code, passed away on Sunday. He was 91. There is an interesting profile of Woodland, and the history of the barcode as we know it, here.http://www.nbcnews.com/technology/technolog/grandfather-barcode-dies-91-1C7594531
