📚 Working smarter, not working harder! In honor of National Library Week, we’re looking back to 1934, when Columbia librarians had to come up with an effective method of moving some 700,000 books from Low Library to newly constructed Butler Library. The solution: a giant slide from the steps of Low Plaza to South Lawn! 📷 1934 Columbia_RBML #ColumbiaUniversity #NationalLibraryWeek
