There is a keyboard. . . . Otherwise it looks like an ordinary desk. In one end is the stored material . Most of the memex contents are purchased . . . Books of all sorts, pictures, current periodicals, newspapers, are thus obtained and dropped into place.

And there is provision for direct entry. . . . There is, of course, provision for consultation of the record by the usual scheme of indexing. If the user wishes to consult a certain book, he taps its code on the keyboard, and the title page of the book promptly appears before him, projected onto one of his viewing positions. A special button transfers him immediately to the first page of the index. Any given book of his library can thus be called up and consulted with far greater facility than if it were taken from a shelf.
