Finding so-called “grey literature” — material from publications not produced by commercial publishers — has always been a challenge for researchers. The most valuable grey literature is often not easily retrieved through a simple query in a search engine; it resides inside a specialized database, buried deep within an association’s web site, or is simply not ranked as relevant by a search engine’s algorithm.
The problem of finding grey literature is not new; research on and discussion about grey lit in the STM field has been going on for years (see, for example, the International Conference on Grey Literature, which has been meeting since 1993). More recently, business researchers are finding that sometimes non-traditional resources have the best — or only — information on a narrow topic or current issue. Following are some of the tricks I use for finding hidden or grey-lit business resources.
