In summary, everyone has unlimited summer access. Recent graduates will automatically have a homepage switch in July and will continue to have almost the same research resources available to them until December 31, 2021 (just minus public records).
CURRENT / RETURNING STUDENTS
You can use your law school accounts for any summer job (big law, small law, government, in-house, your mother's small law firm, etc.). The only restriction on use may come from your employer (some AmLaw100 firms prefer that summer associates use accounts linked to their firm so they can billback to clients).
All points must be redeemed by June 30th, otherwise they will expire. You will retain access to your current account until July 1. On July 1st your account automatically switches from a student to a graduate account until December 31, 2021. The graduate account is essentially the same except they no longer have access to public records and they can no longer earn points.
