Conference proceeding
In academia and librarianship, conference proceeding is a collection of academic papers published in the context of an academic conference or workshop. Conference proceedings typically contain the contributions made by researchers at the conference. They are the written record of the work that is presented to fellow researchers. In many fields, they are published as supplements to academic journals; in some, they are considered the main dissemination route; in others they may be considered grey literature. They are usually distributed in printed or electronic volumes, either before the conference opens or after it has closed. A less common , broader meaning of proceedings are the acts and happenings of an academic field, a learned society. For example, the title of the "Acta Crystallographica" journals is New Latin for "Proceedings in Crystallography"; the "Proceedings of the National Academy of Sciences of the United States of America" is the main journal of that academy. Scientific journals whose ISO 4 title abbreviations start with "Proc", "Acta", or "Trans" are journals of the proceedings (transactions) of a field or of an organization concerned with it, in that secondary meaning of the word. Authorship and editorship. 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 in 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 revisions 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 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 proceedings is distinctly different from an educational textbook. Each paper typically is 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. Conference proceedings are published in-house by the organizing institution of the conference or via an academic publisher. For example, the "Lecture Notes in Computer Science" by Springer take much of their input from proceedings. Conference proceedings also get published through dedicated proceedings series as an edited volume where all their inputs comes from the conference papers. For example, AIJR Proceedings series published by academic publisher AIJR. Publication of proceedings as edited volume in such series are different from publishing conference paper in the journals; also known as conference issue. Increasingly, proceedings are published in electronic format  via the internet or on CD, USB, etc. In the sciences, the quality of publications in conference proceedings is usually not as high as that of international scientific journals. However, in computer science, papers published in conference proceedings are accorded a higher status than in other fields, due to the fast-moving nature of the field. A number of full-fledged academic journals unconnected to particular conferences also use the word "proceedings" as part of their name, for example, "Proceedings of the National Academy of Sciences of the United States of America". Format. Conference proceedings may be published as a  book or book series, in a journal, or otherwise as a serial publication (see ). In many cases, impact factors are not available, although other journal metrics (such as Google Scholar h-index and Scimago-metrics) might exist. Bibliographic indexing often is done in separate bibliographic databases and citation indexes, e.g., Conference Proceedings Citation Index instead of Science Citation Index.
