When I'm sniffing around new territory, I often choose, rather randomly, one general book and then follow its bibliography and notes to other, more specialized works and to the primary source material.
80 percent of our global fish stocks are fully exploited, overly exploited or have collapsed. Two billion people rely on the oceans for their primary source of protein.
It's not at all good when your cancer is 'palpable' from the outside. Especially when, as at this stage, they didn't even know where the primary source was. Carcinoma works cunningly from the inside out. Detection and treatment often work more slowly and gropingly, from the outside in.
Legal immigration is the primary source of low-wage immigration into the United States.
By fostering the economic health and vitality of local communities throughout the country, community banks play a central role in our national economy. One important aspect of that role is to serve as a primary source of credit for the small businesses that are responsible for creating a substantial proportion of all new jobs.
Social Security, for example - I'm 43. I've paid into the system. You know what? That money has been stolen from me. I know that my parents who are on Social Security - they've got to continue to receive it. They're dependent on it. It is their primary source of income.

What I try to do - and I think this is the former librarian in me - is to get primary source material.
