Dear Don:

.

Thank you for your prompt and helpful response to our survey of communications on
occupational health. As you know, one of the objectives of this "inventory" is to
establish a clearing house of information for LIA members. Because you have indicated
that you use a wide range of communication media, we would be interested in seeing
examples of those you employ.
. .
We are especially interested in seeing fi1 ms or slide shows you are using, if they are
different from the material LIA provided you. Should it be inconvenient to duplicate
your audiovisual material, we wi11 return the sample (s) you send us within two weeks.
Your continued cooperation in this research activity is appreciated.
to seeing your materials.

Sincerely,

I look forward
‘
