Our students rely on Wikipedia on their mobile devices or laptops, since it is an extremely rich and broad resource. This article overviews the Chemistry content on Wikipedia and how students can learn to use it effectively as an information resource, critically evaluating content, and learning key information literacy skills. We also discuss how students' information literacy skills can be improved through a class project where students edit Wikipedia articles. Through such projects, students may begin to appreciate where and how chemical information is generated, gathered, developed, and shared in the real world.
