Many databases link to full-text papers for proceedings. Look for a "Document Type" search field. Look for proceedings, abstracts, meeting abstract, conference papers, and proceedings as a document type to search for. If the database does not have a Document Type or similar field, or even if it does, it can be useful to use appropriate document type terms in the general search -- e.g. proceedings, meetings, papers, abstracts, symposia, congresses, expositions, etc. For examples, in Web of Science, limit your search to the Document Type "Meetings." In ProQuest databases, used the Advanced Search option and limit results to "Conference Papers" and or "Proceedings."
Grey literature is the unpublished, non-commercial, hard-to-find information that organizations such as professional associations, research institutes, think tanks, and government departments produce.
Searching for grey literature can be time consuming because it is not usually included in bibliographic databases. Therefore, knowing how to search correctly for grey literature can help you use your time as effectively as possible.
Always use the advanced search option when searching for grey literature. Doing so can save you valuable time by narrowing your search appropriately.
