A paper storage system comprising:
- a rectangular column having an upper portion, a lower portion, a first side, a second side, and a longitudinal axis,
- a first longitudinal groove defined within the first side of the rectangular column,
- a second longitudinal groove defined within the second side of the rectangular column,
- a base rotatably coupled to the lower portion of the rectangular column wherein the base is coupled to a bottom glideable surface;
- a handle assembly attachable to the upper portion of the rectangular column such that the handle assembly is rotatable around an axis which is transverse to the longitudinal axis and such rotation is limited to 180 degrees;
- a plurality of shelving units wherein each shelving unit comprises
- a vertical component sized to slidingly engage and fit within either the first longitudinal groove or the second longitudinal groove;
- a shelf component having at least one frame member;
- a self stopping hinge coupled to the vertical component and the shelf component such that the shelf component can rotate with respect to the vertical component from a closed position to an open position, and
- a plurality of spacers sized to slidingly engage either the first longitudinal groove or the second longitudinal groove.

A paper storage system comprising:
- a rectangular column having an upper portion, a lower portion, a first side, a second side, and a longitudinal axis,
- a first longitudinal groove defined within the first side of the rectangular column having a dovetail cross-sectional shape,
- a second longitudinal groove defined within the second side of the rectangular column having the dovetail cross-sectional shape,
- a base rotatably coupled to the lower portion of the rectangular column;
- a handle assembly rotatably attachable to the upper portion of the rectangular column such that the handle assembly is able to rotate around an axis which is transverse to the longitudinal axis and such rotation is limited to 180 degrees;
- a plurality of shelving units wherein each shelving unit comprises
- a vertical component having a dovetail cross-sectional shape and sized to slidingly engage and fit within either the first longitudinal groove or the second longitudinal groove;
- a wire mesh shelf component coupled to the vertical component, and
- a plurality of spacers sized to slidingly engage either the first longitudinal groove or the second longitudinal groove;
- a plurality of self stopping hinges coupled to corresponding vertical components, wherein each self-stopping hinge comprises:
- one or more tubular structures fixedly coupled to the vertical component wherein each one or more tubular structures has an aperture sized to allow a frame member of the wire mesh shelf component to rotate within the aperture,
- one or more cam-shaped members fixedly coupled to the frame member and aligned with the one or more tubular structures wherein the cam-shaped member includes a flat projecting surface, and
- at least one projection coupled to the vertical component positioned to abut the flat projecting surface of the cam-shaped member to prevent further rotation of the cam member.
