Grey literature is produced by researchers and authors, based in organizations often funded by the public, whose main purpose is not commercial or professional publishing, which creates problems for its distribution, findability and use. There is no investment in organizing or managing this literature, because it isn’t making anyone any money. The documents are usually published to websites or distributed via email newsletters and discovered through search engines or possibly repositories or libraries. Sometimes they aren’t published at all, but only distributed via internal channels of government and organizations.
