Our visit to the New York Public Library was really instructive because it put all the students in contact with physical maps of the Vinegar Hill area. (Before, we were mainly looking on digital versions of maps of that region). We had access to entire books of maps so, just by flipping a couple of pages, we also saw many maps from adjacent areas and maps from different decades. It was interesting to learn that those map books used to be updated just by gluing paper with the new information on top of the old maps. Also, it was really fun checking Google Maps and contrasting it with the books, comparing what was like in the past and how it is right now.
