Teachers and colleges initially barred Wikipedia as an unreliable source; Middlebury College's history department formally banned citing it in 2007.

Wikipedia became a standard first stop for research, with schools mandating verification against primary sources rather than banning it.
Shows the common arc from outright prohibition to structured, supervised use that districts may now repeat with AI.
