at least one vertical support member having a first end and a second end, wherein the first end is coupled to the base; a handle component coupled to the second end of the at least one vertical support member; at least one fixed or removable shelf unit comprising a first shelf member extending from the vertical support member at a predetermined angle. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The system of claim 1, 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 the frame member of the 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. ### Claim 3 (depends on 1) The system of claim 1, wherein the first longitudinal groove and the second longitudinal groove have a dovetail cross-sectional shape. ### Claim 4 (depends on 3) The system of claim 3, wherein the vertical component has a cross-sectional dovetail shape sized to fit within the first longitudinal groove or the second longitudinal groove. ### Claim 5 (depends on 1) The system of claim 1, wherein the first longitudinal groove is laterally offset from the second longitudinal groove. ### Claim 6 (depends on 1) The system of claim 1, wherein each shelf component is formed from a flexible material and a support frame supporting the flexible material. ### Claim 7 (depends on 6) The system of claim 6, where the flexible material is selected from the group consisting of a wire mesh, canvas, leather and faux leather. ### Claim 8 (depends on 1) The system of claim 1, wherein each shelf component is formed from a material selected from the group consisting of wood, bamboo, laminated wood, metal, laser cut metal, polished aluminum, and plastic. ### Claim 9 (depends on 1) The system of claim 1, wherein the rectangular column is formed from a material selected from the group consisting of wood, bamboo, laminated wood, metal, polished aluminum, and plastic. ### Claim 10 (depends on 1) The system of claim 1, wherein the handle assembly is configured to removably couple to the upper end of the longitudinal support, the handle assembly comprising a handle having a hinge element to allow the handle to rotate around a lateral axis through an angular rotation path of approximately 180 degrees. ### Claim 11 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. ### Claim 12 (depends on 11) The system of claim 11, wherein the base is coupled to a plurality of retractable rollers.
