Baylor's libraries collections are very strong, but we don't have every book in the world. To see what books exist out there, use WorldCat (see link below). Using WorldCat is also the first step to borrowing that book (no matter where it is in the world) just as if Baylor owned it. Books that are found on WorldCat can be borrowed by making requests through Osofast (http://www.baylor.edu/lib/ils/).
The Who's Buying series is based on unpublished data collected by the Bureau of Labor Statistics' Consumer Expenditure Survey. It examines how much Americans spend on various products and services by the demographics that count: age, income, high-income households, household type, race and Hispanic origin, region of residence, and education. To round out the spending picture, it also presents who-are-the-best-customers analyses of the data, showing the demographics of spending at a glance. The individual titles of this series can be found by searching the library's online catalog for the title "Who's Buying".
