At my place of work, we’re just beginning a massive weeding project as a part of the larger new library building project. We are hoping to weed the entire collection for, effectively, the first time in the history of the library. Needless to say, it’s kind of going to own our lives for the next 18 months.
As a part of this, my awesome co-worker Andrea created this chart showing the distribution of publication dates for our collection. The massive amount of 1800’s is from our Early English Books Online collection, but the rest of it shows a pretty great distribution of “when did the library have funding” over the decades.
