NEW NEWS LETTER INDEX
When the News Letter was first published, it was issued as one-time
reading material which could be destroyed after reading. It is now
apparent that many Customer Engineers have retained many or all
issues and desire a new index to locate past News Letter items.
Here it is! A NEW NEWS LETTER INDEX! No more fumbling for
News letter items. Now it is easy to locate past News Letter items
filed in the Branch Office.
This Index is being sent to all Customer Engineers for the convenience
of those who like to retain past issues. Copies of previous News
Letters are not avai lable for distrubution.
