Grey Literature Clearing House

Trying to understand what Grey Literature is? In a nutshell, it's all that stuff that you can't find through library catalogs, article databases, or other standard sources of scholarly information. Grey literature includes online journals, blog posts, self-publishing on the web, and much more. For those of us in the technology world, 90% of what we need for projects and research comes from grey literature...not standard print sources.
