"Widener" was the "first" library I visited when I came to Harvard University for my Ph.D. dissertation research as a special Turkish fellow! I was so fortunate to begin to learn who a scholar is, what his/her role/mission/responsibility to promote new knowledge "production", etc. within such an excellent scholarly research atmosphere! Though "this magnificent library is still closed due to the pandemic, its doors are open to everyone through its virtual tour! Thanks Harvard!
