The Electronic Resource Directory - Version 1.0 There is not much to running this electronic resource directory. Just unzip all the files to your directory of choice and go there and type "ERD". All the rest is self explanatory. The resources in the database were developed by the Massachusetts Commission for the Blind and will be kept updated by the agency. Periodic updates to the databases will be issued by MCB on its BBS (617)-451-5327. That's basically it. How's that for short docs?
