Grey Literature

Grey literature is research material that has not been formally published. By its nature, grey literature is hard to locate and the content is of variable quality. 

It is recommended that grey literature sources are considered when undertaking a systematic review. Some sources of grey literature are listed on this page.



PsycExtra is a database of grey literature material relating to psychology, behavioural sciences and health. Full text is available for the majority of records - look out for the Ovid Databases PDFs link to access the full text.
