Redaction is a form of editing in which multiple source texts are combined (redacted) and subjected to minor alteration to make them into a single work. Often this is a method of collecting a series of writings on a similar theme and creating a definitive and coherent work. To redact can also mean to select or adapt (as by obscuring or removing sensitive information) from a document prior to publication or release.
