You can go here to view the two pages from the book that list all the buildings and art in the book : https://columbus.in.us/docs/book/timeline.pdf This is the most up-to-date list. I would also suggest you stop by the Visitors Center for help with any other questions and to pick up the official Columbus Guide, which maps out all of the sites. Hope you enjoy your visit!
Please check out 52weeks.rickeyberkey.org/columbus-history-timeline for up to date architecture and historical info; it's to date through 2017. Also, don't forget the 2nd Street bridge - obviously not a building but still impressive. Built in 1999.
