Abstract: A reserve system for library articles includes (i) a “reserved article” storage system for temporarily storing and automatically retrieving reserved articles, (ii) a conveyance to deliver the library articles to either the library staff or an originating library patron, and (iii) at least one controller system to manage all system functions. The reserved article storage system may be a modular system that includes: (i) one or two “storage racks,” each comprised of a plurality of “storage bins” for temporary article storage, and (ii) one “vertically positionable retrieve and transport assembly” for article retrieval from a selected storage bin from a selected storage rack.
