RefWorks has the ability to search hundreds of catalogues and databases, and to export selected references, right from your RefWorks account. You can access this option from the "Search" menu dropdown.
Select your database, and the maximum number of references to download. You can perform a keyword search, or search for specific items in the Advanced Search. To add an additional field, click the green circle.
You can export selected references, a page of results, or the entire results list, to your RefWorks account.
