Abstract: Compact shelving consisting of a cluster of elongated, upstanding stacks of shelves juxtaposed side by side are accessible by mounting each elongated stack on an elongated carriage having rear rollers guided in elongated floor tracks coextensive in length and width with the stack and hidden thereunder. There are plastic tired wheels under the front of the carriage so that the carriage and stack can be moved, endwise on a track out of the cluster to expose the open side shelves. Front shelves increase the storage capacity. A removable crank on the front end, through twist-belt power transmission, advances and retracts each stack.
