Just saw Libraries: How they stack up from OCLC. It has lots of good comparisons of libraries to other “stuff” – here are a few good ones:
U. S. public library cardholders outnumber Amazon customers by almost 5 to 1 (Amazon – 30 million customers; public library cardholders – 148 million).
Amazon ships around 1,500,000 items per day; U. S. Libraries circulate 5,400,000 items per day.
And a completely silly one:
– Librarians worldwide: 690,000
– Population of Bahrain: 656,000
