Whether you're wondering what you can do for Harvard, or what Harvard can do for you as an alum, here are some ideas.
In 2015, Harvard introduced Harvard Key, an identity management system that allows Harvard affiliates, including alumni, to authenticate themselves for many purposes, from accessing the library to voting in elections to registering for reunions. Have you noticed that some web sites allow you to log in with your Google, Facebook, or Twitter password? Harvard Key is the same thing for Harvard. Some classmates have run into problems signing up for Harvard Key, but it does work and is very useful. If you have trouble signing up, contact the Harvard IT Help Desk.
Alumni also can apply to visit Harvard libraries in-person free of charge, or pay for borrowing privileges.
The library also operates an Ask a Librarian service. We asked a librarian what services are available to alumni, and a librarian answered that alumni are welcome to use the Ask a Librarian service, either to ask a reference question or make an appointment with a reference librarian.
Alumni are eligible for complimentary membership in the Harvard Faculty Club. Membership allows you to dine at the Faculty Club (not a great deal) and reserve guest rooms (prices not published on the website). Even if you don't think you would use this benefit, or don't even live in Boston, it might be worthwhile for reciprocal benefits, especially since there's no cost.
Office of Career Services
The Office of Career Services is specialized in helping graduating or recently graduated students identify career paths. Services for alumni more than five years post-graduation are limited to an annual resume review. They do have online resources that might be useful for someone considering a career change. Alumni can also volunteer to serve as a resource for current students and recent graduates.
