Selecting and collecting papers for conferences is organized by one or more persons, who form the
editorial team. The quality of the papers is typically ensured by having external people read the papers before they are accepted for the proceedings. The level of quality control varies considerably from conference to conference: some have only a binary accept/reject decision, others go through more thorough feedback and revision cycles (
peer reviewing or refereeing). Depending on the level of the conference, this process can take up to a year. The editors decide about the composition of the proceedings, the order of the papers, and produce the preface and possibly other pieces of text. Although most changes in papers occur on the basis of consensus between editors and authors, editors can also single-handedly make changes in papers. Since the collection of papers comes from individual researchers, the character of a proceedings is distinctly different from an educational textbook. Each paper is typically quite isolated from the other papers in the proceedings. Mostly, there is no general argument leading from one contribution to the next. In some cases, the
editors of the proceedings may decide to further develop the proceedings into a textbook. This may even be a goal at the outset of the conference. ==Publication==
