Epistolary novel
An epistolary novel is a novel written as a series of documents. The usual form is letters, although diary entries, newspaper clippings and other documents are sometimes used. Recently, electronic "documents" such as recordings and radio, blogs, and e-mails have also come into use. The word epistolary is derived from Latin from the Greek word ἐπιστολή epistolē, meaning a letter (see epistle).
