Twenty Critical, Authoritative, and FREE Electronic Databases
by Jeffrey Meyer

Online searching provides opportunities and challenges. How reliable is an online source? Where can I find authoritative information amid the millions of search results? Fortunately, many authoritative institutions have made their wellsprings of data freely available to the online searcher. Many of these databases are provided by public institutions, meaning that there is no entrance fee or subscription required to access their treasures. 

These free, online resources are important tools for the librarian’s kit, giving professionals fast answers from good sources. Librarians don’t need to wade through the millions of jumbled, anonymous, Wiki-style answers provided by online search engines. Speed and authority are often of the essence in reference work, and these 20 databases give librarians fast and authoritative answers for a wide range of topics. The following resources amount to a free electronic reference shelf. They have been grouped into topical subjects. 

DEMOGRAPHICS

1. American FactFinder, U.S. Census Bureau
factfinder.census.gov

How many people live in Ohio? What is the population of Buffalo, N.Y.? What percentage of the population is elderly? What is the median household income in St. Louis? All of these questions and more are easily answered with American FactFinder’s excellent searchable database of every town, city, county, and state in the U.S. FactFinder is a very useful source for official reports, homework, and grant writing. 

2. The World Factbook, CIA
cia.gov/library/publications/the-world-factbook

The CIA has compiled a veritable encyclopedia of world geography. While the U.S. Census Bureau focuses on demographics within the U.S., the CIA casts an international net. The World Factbook can provide quick answers to many questions about the nations of the world. How many people live in Ireland? What percentage of Canada’s energy consumption comes from renewable resources? How do China’s defense expenditures compare to those of the U.S.? Obtaining substantial population, economic, and historical data about any nation is just a click away with The World Factbook.

3. UNESCO Institute for Statistics

UNESCO also provides downloadable PDFs of official reports on these important issues.
