vintageTEK has received a number of Engineering News publications for our Library. The intact ones are dated from 1978 with a front cover title Engineering News and were Company Confidential at the time.
We are curious about two things. First the format of Engineering News appears to be almost identical to later Technology Report, and since their date date preceed Technology Report - we are assuming Technology Report succeeded Engineering News?
Secondly, we have a number of articles torn from these documents, with a page color that matches neither of the whole publications that we own. The pages are tan or light brown in color. Any ideas what circa document the tan pages were torn from?
