Grey literature refers to documents produced and published by governments, NGOs, think tanks, research centres, and other groups. It can incorporate everything from a one-page brochure to a 500-page book, and the intended audience may be the public, specific stakeholders, government representatives, or academics. Because grey literature does not go through the same peer-review process used by scholarly journals, it is not usually considered to be scholarly even if the same rigorous research and analysis is used. In some cases, grey literature may be considered to be primary sources; in other cases it may be secondary or tertiary sources.
News and media databases provide articles on all topics, give opinion, background, quotes, etc. and many times provide unique content not found in other databases to include Canadian magazines, newswire, newspaper, and editorials. Search ProQuest databases CBCA and Canadian Major Dailies separately or together, CPI.Q for unique content, and consult the list of alternate News Databases to search individual newspapers e.g. St. Catharines Standard, historical newspapers e.g. Globe & Mail, New York Times, Time (London), and regional papers. Search LexisNexis and Factiva to find regional, Canadian and international real time, full text articles. Be sure to consult the appropriate guide to make sure you know how best to search.
