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 examples). 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.
