Library Data

Collecting and analyzing data about libraries and their future .
The shape of public libraries
Here I picked library visits, but if you pick pretty much any feature of public libraries and plot out a frequency histogram, it will look pretty much just like this.  What’s surprising about this data? It has a very strong positive skew, which in the case means that for the most part, public libraries are small.  There is of course a very long tail of large libraries (in fact I trimmed off some of the largest just because it became so hard to see the rest).
