One link for several very short instructional videos that show you how to export citation information to RefWorks from EBSCOhost databases, JSTOR, CSA databases, Project Muse, Google Scholar and Books, UTA Library Catalog, LexisNexis Academic, and WorldCat First Search.
The export function from the Libraries' new catalog interface, Summon, is not intuitive at all, and the company that makes Summon is working on this problem. However, in the meantime, you can take a look at this blog post from the Libraries at University Campus Suffolk for step-by-step instructions on how to get your citation information out of Summon and into RefWorks.
You can export references from a Shared Folder or Shared RefWorks account into your own RefWorks account. This is especially useful for group projects in which all group members have done research and would like to compile their references into a single RefWorks account.
