ELD maintains a published directory of its members.
PDF: ELD Directory of Members.
The password for the Directory can be found in an email on ELD-L or by contacting Paula C Johnson: firstname.lastname@example.org, if you have questions, corrections, or would like a copy. The directory is only available to ELD members.
You can search for members from the ASEE member directory. Click on Login and have your ASEE member number handy (on the mailing label from your copy of Prism).
