%Since BibTeX does not appear to have a built in entry

 %for citing websites (what kind of design is that?),

 %I decided to stick websites in with articles, and to stick

 %the URL in the journal field. This is not technically correct.

 %I did something largely similar with Walter Lewin's video lectures,

 %(which are wonderful), posted online through MIT OCW. Since a

 %'proper' way of citing it wasn't built in, I made one up. If

 %you're doing a bibliography where correct formatting is very

 %important, you'd do best not to follow my example. Otherwise,

 %I think it's good enough.
