A system where library vendors send collection development personnel items to be approved for purchase.
An arrangement by which a publisher or wholesaler assumes responsibility for selecting and supplying, subject to return privileges, all publications, as issued, which fit a library's pre-established collection profile. The profile usually specifies subject areas, levels of difficulty, formats, price ranges, languages, etc. Some plans provide advance notification slips, instead of sending the publications themselves. Compare with blanket order. See also: collection development.
