Were schools banning search engines? I remember teachers recommending Dogpile (because it would combine search engines), and we did some computer lab stuff in the 00s, but there was no one saying that we should ignore search or the internet altogether.
In middle school I remember being assigned a book report that would include the author's biography. I'd just finished a book (The Gammage Cup) and of course my local library did not have any information about the author. So in that situation it was assumed that you would learn traditional research methods, but also that you would just pick a classic book where the information was readily available.
