Bowie’s first dictionary was likely much like my first dictionary — an eight-inch-thick tome. It was big, heavy bitch with thin-skinned pages that stuck to your fingers, covered with a stew of spider-fine print. I’ve grown up, and the dictionary has shrunk. The big, heavy book first became a couple of featherweight CD-ROMs; then the CD-ROMs thinned into weightless internet. This disappearing act is a paradoxical one, for as the dictionary has journeyed from analog to electronic to digital, it both holds more and is easier to use.
