The TTUHSC Libraries have made the resources RefWorks and EndNote available for students to use. They allow you to import citations to the program, sort your citations into folders, and share folders with other RefWorks/EndNote users. RefWorks is a cloud-based program, i.e. there's nothing to download, you just log in. EndNote is available in a desktop version (i.e. download) and in a web version (like RefWorks).
Both programs allow you to download a component into Microsoft Word on your computer. In both programs, this allows you to insert your citations from the program into your paper, and in any style you choose.
