In early October 1926, almost 60 librarians from 25 countries gathered in Atlantic City and Philadelphia to celebrate the 50th anniversary of the American Library Association along with more than 2,000 American librarians. By all accounts, the conference was a great success. But the best part of this all-expenses-paid trip to the U.S. didn’t happen during the actual meeting: When the conference ended, about 30 international delegates went on a multi-state excursion, visiting 12 cities in the span of two weeks.
