"The memex consists of a desk (...): On the top are slanting translucent screens, on which material can be projected for convenient reading. There is a keyboard, and sets of buttons and levers. (...) Most of the memex contents are purchased on microfilm ready for insertion. Books of all sorts, pictures, current periodicals, newspapers (...) And there is provision for direct entry. On the top of the memex is a transparent plate. On this are placed long hand notes, photographs, memoranda, all sorts of things. When one is in place, the depression of a lever causes it to be photographed onto the next blank space in a section of the memex film; (...) There is, of course, provision for consultation of the record by the usual scheme of indexing. (...) As the user has several projection positions, he can leave one item in position while he calls up another. He can add marginal notes and comments (...), just as though he had the physical page before him."[11]
