I listed 684 conferences held in 2011 (up from 653 in 2010) on the ITI Conference Calendar, and mentioned 241 of them in my 11 monthly columns. As shown in the figure below, 2011 followed the usual pattern, with the busiest periods of the year in the spring and fall. The spring period, April through June, had 192 conferences, and the fall period, September through November, had 240. Each of these periods accounts for approximately 1/3 of the yearly total. And also as usual, dips were observed in the year-end months and in July.

Conferences were held in 209 different cities in 21 countries. Here are the cities in which 5 or more conferences were held.

London heads the list, as it usually does, followed by Washington and New York. The reason San Juan, PR appears is that it was the location of the IFLA annual conference and its associated meetings.
