Usually, the paper is divided into sections for each of those major groupings (labelled A, B, C, and so on, with pagination prefixes yielding page numbers A1-A20, B1-B20, C1-C20, and so on). Most traditional papers also feature an editorial page containing editorials written by an editor (or by the paper’s editorial board) and expressing an opinion on a public issue, opinion articles called “op-eds” written by guest writers (which are typically in the same section as the editorial), and columns that express the personal opinions of columnists, usually offering analysis and synthesis that attempts to translate the raw data of the news into information telling the reader “what it all means” and persuading them to concur. Papers also include articles that have no byline; these articles are written by staff writers.
