Abstract: A vertical support shaft projects down from the underside of a telephone booth shelf and supports the inner end of an arm swivelable horizontally about the shaft. The outer end of the arm is hingedly coupled to a telephone directory binder so that the binder is pivotable about a horizontal axis at such end and transverse to the arm's centerline. The binder's centerline is parallel to a reference line passing through such axes at an acute angle b. When the arm is on "in" position the binder is stored beneath the shelf in primary alignment with its width. When the arm is pulled out and the binder is pivoted out, up and over, the binder goes through a motion equivalent to an angular displacement of 2b to come to rest face-up with an alignment parallel to its former widthwise alignment.
