Are you interested in grey literature on aspects of urban and public health? If so, you may want to check out the Grey Literature Report, published for free by the New York Academy of Medicine, online at www.nyam.org/library/greyreport.shtml.
The Grey Literature Report contains details of reports published by non-commercial organisations such as government agencies, non-profit non-governmental organizations, universities, independent research centers, and international organizations. The subject scope includes health and science policy, public health, health of minorities and special populations and those areas of general medicine and disease in which the Academy has research interests. The focus is on research material, not consumer health material. More details of the content and collection development can be found at www.nyam.org/library/greycolldev.shtml.
Grey literature was defined at the Fourth International Conference on Grey Literature (GL '99) in Washington, DC, in October 1999 as "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."
