Boston University: “It’s that time again. Twice a year Mugar Memorial Library is transformed into BU’s ground zero … The Mugar staff, which includes some 200 student-employees, puts out candy and Post-its with words of encouragement. And during the end-of-semester frenzy, the library provides van service from midnight to 6 a.m. for any student living on campus who needs a ride home. There are other stress-busters, too: visits from Rhett the Terrier and from real (What! Rhett isn’t real?) four-legged creatures, among them Ana, a two-year old Great Pyrenees therapy dog, the undisputed star attraction.”
