Non-conventional literature (NCL, also called ‘grey literature’) comprises scientific and technical reports, patent documents, conference papers, internal reports, government documents, newsletters, factsheets and theses, which are not readily available through commercial channels. NCL specifically does not include normal scientific journals, books or popular publications that are available through traditional commercial publication channels.

NCL can be more difficult to search and access than traditional literature. It is typically not as well cataloged, and not collected by libraries as extensively.

Among academics, publication in "grey literature" has a lower status than publication in peer-reviwed journals.

-==Library Setting==
-In a library setting, it is  important to learn about the grey literature especially that it might be beneficial for the user yet hidden in most cases.
-Actually, the internet has modified the role of the libraries as a physical place as well as the way they acquire information. Users’ preference is for the online sources, and statistics demonstrate that the number of internet surfers is constantly increasing. According to the Scientific American, statistics show that the number of Americans who use the internet -including search engines- is “4 million per day”. However the users might be unaware of the way search engines gather the information they need.
-In fact, Search engines use a program, [[web crawler]], and "create a copy of all the visited pages for later processing by a [[search engine]], that will index the downloaded pages to provide fast searches."
-Not all information is visible by the search engines. Some pages cannot be spidered. This material is called Grey Literature, which is “commonly defined as any documentary material that is not commercially published and is typically composed of technical reports, working papers, business documents, and conference proceedings.” In a library, it consists of pamphlets, library catalogs and thesis, conferences etc., Due to the nature of Grey literature, librarians have had difficulty acquiring and making it accessible.”
-New Trend A new trend today is the open access movement to invisible material, where many organizations are providing free online access to their selective resources.
