"The MIT Video website - developed and maintained by the MIT News Office - aggregates and curates video produced by the Institute's offices, laboratories, centers and administration. This includes feature and editorial videos, event recordings, academic content and more. Each day, the editorial team at MIT Video selects one or more videos to "spotlight" based on the videos' content, production value and timeliness"
"The National Gallery of Writing is a virtual space-a website-where people who perhaps have never thought of themselves as writers-mothers, bus drivers, fathers, veterans, nurses, firefighters, sanitation workers, stockbrokers-select and post writing that is important to them. The Gallery accommodates any composition format-from word processing to photography, audio/video recording to text messages-and all types of writing-from letters to lists, memoirs to memos"
