Single source publishing, also known as single sourcing publishing, is a content management method, often referred to as multichannel content management, which allows the same source content to be used across different forms of media and more than one time. The labour-intensive and expensive work of editing need only be carried out once, on only one document; that source document can then be stored in one place and reused. This reduces the potential for error, as corrections are only made one time in the source document. Single-source publishing is sometimes used synonymously with multi-channel publishing though whether or not the two terms are synonymous is a matter of discussion.
