- Sometimes, but not often, the posting medium is a bound sales book, a bound cash book, or bound journal of merchandise credits. In modern institutions Loose Leaf units are generally used, because they are easily handled and readily classified. Loose Leaf units for each transaction are more adaptable as posting mediums than bound book or continuous Loose Leaf records; they are more easily sorted, classified and arranged to suit the requirements of modern ledger posting. Unit records can be readily sorted alphabetically by customers' names, territorially, numerically, by salesman, by goods, by departments, or by branches, depending upon the nature of the business and the particular way the ledger accounts are classified. A total of items to be posted (predetermined total) to the Ledger is usually provided by the Auditing Department. With unit records it is easy to get such a predetermined total. This is further explained elsewhere under "Control."1918 Elliott-Fisher Way Bookkeeping by Machinery. A Text Book for the Guidance of the Novice or Expert. Elliott-Fisher Company, Harrisburg, Pa.

- 1987 Howard Fosdick: VM/CMS Handbook for Programmers, Users, and Managers Page 114 Pub. Hayden Books Card readers, card punches, and printers are unit record devices. They must be dedicated solely to a particular program for the duration of that program's execution. Otherwise, input to (and output from) different programs would be interspersed. These dedicated devices render a multi-user computer system slow and inefficient because programs must wait for access to devices they require.
