A hundred years after Marie Curie received her Nobel Prize in Chemistry, this arm of science is pointing the way to a more sustainable future. Growing movements like green chemistry, which strives to create alternative and new chemical reactions that produce no harmful waste products, and molecular engineering hold great potential for industry, the environment, and crossover fields like medicine and physics. To celebrate chemistry's promise and achievements over the past century, 2011 has been declared the International Year of Chemistry (IYC) by the United Nations Educational, Scientific, and Cultural Organization (UNESCO) and the International Union of Pure and Applied Chemistry (IUPAC). This is a great time to update one's chemistry collection and celebrate the IYC 2011 theme, "Chemistry: Our Life, Our Future." The key to collection development is to know one's service population. All collections need a few good general chemistry references. Most libraries also need an authoritative chemistry encyclopedia, although small libraries might rely on a good science and technology encyclopedia. Subscription databases can also be invaluable. The author presents a selective bibliography that will help public, high school, and college libraries celebrate a century of chemistry, or simply identify the most important titles to update their collections.
