Grey literature in the context of "Proceedings"

Academic publishing is the subfield of publishing which distributes academic research and scholarship. Most academic work is published in academic journal articles, books or theses. The part of academic written output that is not formally published but merely printed up or posted on the Internet is often called "grey literature". Most scientific and scholarly journals, and many academic and scholarly books, though not all, are based on some form of peer review or editorial refereeing to qualify texts for publication. Peer review quality and selectivity standards vary greatly from journal to journal, publisher to publisher, and field to field.

Most established academic disciplines have their own journals and other outlets for publication, although many academic journals are somewhat interdisciplinary, and publish work from several distinct fields or subfields. There is also a tendency for existing journals to divide into specialized sections as the field itself becomes more specialized. Along with the variation in review and publication procedures, the kinds of publications that are accepted as contributions to knowledge or research differ greatly among fields and subfields. In the sciences, the desire for statistically significant results leads to publication bias.

In academia and librarianship, conference proceedings are 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 Neo-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.

A newsletter is a printed or electronic report or news concerning the activities of a business or an organization, that is sent to its members, customers, employees or other subscribers, or a communication containing individuals' personal opinions or interests.

Newsletters generally contain one main topic of interest to its recipients and may be considered grey literature. E-newsletters are delivered electronically via e-mail and can be viewed as spamming if e-mail marketing is sent unsolicited.

A white paper is a report or guide that informs readers concisely about a complex issue and presents the issuing body's philosophy on the matter. It is meant to help readers understand an issue, solve a problem, or make a decision. Since the 1990s, this type of document has proliferated in business. Today, a business-to-business white paper falls under grey literature, more akin to a marketing presentation meant to persuade customers and partners, and promote a certain product or viewpoint.

The term originated in the 1920s to mean a type of position paper or industry report published by a department of the UK government.
