Described is a document-rack structure consisting of a supporting base (10), a wall (12) integral with the supporting base and a multiplicity of divider panels (15) attached by means of tongue-and-groove joints to the supporting base (10) on one side and to the wall (12) on another side, so that between them and together with the upper surface (11) of the supporting base they come to form separate document-rack spaces. The upper surface is shaped in such a manner that the bottom surface of at least some of these spaces is inclined with respect to the horizontal. The structure renders possible an orderly arrangement of cartaceous documents and ready visibility and accessibility of these documents.
