"Grey literature is that which is produced on all levels of government, academics, business and industry in print and electronic formats, but which is not controlled by commercial publishers. » The definition emphasises two major characteristics of this type of information: on the one hand its universality and ubiquity and, on the other the difficulty of identifying and accessing it by means of conventional publishing commercial distribution."
