Citation management software, RefWorks, will no longer be available from University Libraries at the end of June 2017. Users should migrate their projects to other free applications before then. Mendeley and Zotero are two that can work for that task. Both have their own guides, and there is more information on this libguide page: http://libguides.wmich.edu/refworks
It is important that users of RefWorks get their information out of that application before it is no longer available.
Citation managers (like Mendeley and Zotero) let you save, organize, and share your research literature. You can import citations from virtually any library database, and in most cases attach the full text PDF as well. You can organize your research by using folders and tags, which also enhances your ability to retrieve the citation you need to refer to. Both Mendeley and Zotero also have PDF readers to allow you to make notes and highlight the text online.
