Flat file drawer cabinets are a practical, cost-effective, and safe storage system for collections containing numerous, large paper objects. Flat file drawer cabinets are durable and relatively waterproof. Oversize flat files should provide storage for most of the largest paper objects found in a typical collection. In addition, smaller objects can be grouped in stacks within drawers. These objects may include drawings on paper (or drafting film), maps, posters, and other printed materials. If the object is larger than the largest commercially available flat file drawer cabinet, or if the objects are so few in number as to not warrant the purchase of a special cabinet, small scale storage system may be used. These systems include storing small numbers of objects flat in portfolios or rolling them into tubing.
