Abstract: An automated library article terminal is externally operable by the user, to, through a delivery chute mounted and arranged to deliver articles through an external wall, automatically stock, vend, and selectively accept return of and re-stock, so that they can be re-vended, a plurality of reusable articles each having a unique code. A memory stores information comprising the location of the plurality of articles in the terminal. A control is coupled to the memory and is responsive to operation of the terminal by a user to generate control signals. A vertical track member has a rotational drive responsive to the control signals for revolving the vertical track member about a given axis. A vertical lift member is mounted for vertical movement on the vertical track member. A vertical drive is responsive to the control signals for vertically moving the lift member relative to the vertical track member.
