Subject:   SDS Records Referenced by Others with Attribution

Dear Ron,

Thanks for the heads up in your letter today requesting permission to use analysis in SDS records on Tom Landauer's excellent book The Trouble with Computers, evidently for a professional article and/or event. Glad to see others are paying attention to professor Landauer's ideas on user centered design. The presentation by Helen Maskery on January 17 earlier in the year that discusses UCD, and attributes your work and Amy Dillon's contribution, is outstanding. Pleased to grant permission to use SDS for advancing your important work, as shown in the record today.
..
Best of luck with your conference.

Sincerely,

THE WELCH COMPANY
