XII.2 HathiTrust Digital Library
The HathiTrust Digital Library is a collective “elephant’s memory” or storehouse of knowledge. Run by a consortium of international research libraries, it serves as a shared and growing repository for digital copies of more than 14 million publications that span 2000 years.
Visualization software developer David Reagan, curator Lisel Record, and information scientist Katy Bӧrner developed this visualization to delve into the geographic and temporal diversity of the collection using freely available metadata.
Yellow circles show publication locations, with the size of the circle showing how many publications were printed in that location. Lines connect publication locations to places where that language is spoken, illustrating the connection between publication location and potential readers.
If you look at publications from the years 1200-1400 you see the prominence of Persian science and culture reflected in the high number of publications from Iran and other Middle Eastern locations. If, on the other hand, you look at publications from the last 50 years, a colorful swirl of publications bubble up from many regions and flow to readers around the globe.
