All databases offer some sort of export-to-citation-manager function. Some are straightforward in how they work; other are not. SciFinder Scholar is one of the others. It, like many older databases, has its own set of quirks. The good news is that once you learn how to handle one quirky database, you'll be equipped to figure out any of the others.
Here are steps that will work. First, log into SciFinder Scholar and Refworks on two separate tabs.
NOTE: Single citations from SciFinder (both Scholar and N) may export directly into RefWorks without problems, but exporting one citation at a time defeats the purpose of exporting. You'll save time and effort by creating multi-citation files.
NOTE: if you are ever working with a database that does not include a direct export to RefWorks or any other such program, go to whatever export function that they provide and look for the RIS option. RIS files are designed for citation managers. As you may notice in RefWorks, there many different types of RIS files available. If your source is not listed as a specific source of RIS files, choose the basic one - plain RIS format.
