Usage of library Drupal modules

Edit: Failed to include (my own) HILCC module. How embarassing.

Out of curiosity, I did a quick sampling of usage stats (according to Drupal.org) of different library-related Drupal modules. I left out some that didn't have usage information or are not hosted on D.O. and of course, didn't count many other modules useful to libraries (like Apache Solr, booking modules, etc.)

These stats also reflect only those sites that have module update tracking turned on; it'd be a good question to ask Drupal library service providers what's their best practice on that.
