The ’Grey’ Literature

> Current Page
Updated 2019-11-24

 What is ’grey’ literature?

The 'grey' literature is written and published material (such as analytical or survey reports) that may be difficult to trace via conventional channels such as published and peer reviewed journals It is usually not published commercially or may not be not widely accessible. It is nonetheless a very important source of information in food composition, because it is original and recent. Examples of grey literature include technical reports, e.g. technical reports from government agencies or scientific research groups, working papers from research groups or committees, etc.

The reports are usually written in the official laguage (languages) of the issuing organisations, and this may for non-English languages limit broad access to reports. Furthermore, the reports may be difficult to find as they are not necessarily covered by the commercial publishers and public search engines, like scientific literature.

As the analytical or survey reports are of extreme importance in food composition work, below is a collection of the most recent works by government agencies, research instititutes and laboratories. Most of the reports are available for download (marked by Download indication with hyperlink.). There are however a few reports mentioned below, for which it has not been possible to find a hyperlink.
