Does a university like Columbia have a yearbook with pictures of its students?
So far this is all I have found from his years at Columbia:
‘People who knew him around that time describe a reserved, monkish man, uninterested in the extracurriculars of New York student life: bars, socializing, gossiping. William Araiza was in a political-science seminar with Obama their senior year, and what he remembers most is Obama’s detachment. “I don’t want to imply he was intentionally aloof, he just seemed like he wasn’t part of the college gang,” Araiza says. “He was the kind of guy who didn’t live in the dorms, didn’t hang out on campus.”’
found at the following url but I’ll keep looking.
