Yes, we use it all the time to convert our EAD finding aids to MARC. We 
  import them into OCLC connexion.  What version of MARCEdit are you 
using? (Click on Help--About in MARCEdit).  If you are using version 4.6 
(correct me if I'm wrong, Terry), converting from EAD to MARC 
communications format was a two-step process using the built-in GUI. 
You first had to convert from EAD to MARCXML, then from MARCXML to MARC. 
  With the new MARCEdit.Net version, you can do this in a single step. 
You can download the new version here:

The included XSL stylesheet may need some tweaking for your institution. 
  You are welcome to try mine also to see which one works best with your 
encoding.  This is available here:
