Recension is the practice of editing or revising a text based on critical analysis. When referring to manuscripts, this may be a revision by another author. The term is derived from Latin recensio ("review, analysis").
In textual criticism, particularly Biblical scholarship, the count noun recension may be used to refer to a family of manuscripts sharing similar traits; for example, the Alexandrian text-type may be referred to as the "Alexandrian recension". The term recension may also refer to the process of collecting and analyzing source texts in order to establish a tree structure leading backward to a hypothetical original text.
