While you're at it... what's the percentage overlap between those lists? Using the list of subscribers as input instead of domains, I wrote a Perl hack (evaluate.pl) to answer the overlap question. [1] $ ./evaluate.pl Code4Libbers = 1706 NGC4Libbers = 2115 union (all) = 3394 intersection (both) = 427 percent in Code4Lib = 25% percent in NGC4Lib = 20% In other words, there are 1,700 of us Code4Libbers and there are 2,100 NGC4Libbers. Not counting duplicates, the population of both lists is 3,400. Four hundred (400) of us are on both lists. Consequently, 25% of us subscribe to NGC4Lib and 20% of NGC4Libbers subscribe to Code4Lib. BTW, over the past year or so, the Code4Lib list continues to grow by one or two people per week, while the NGC4Lib list has seemingly reached a plateau.

(In comparison NGC4Lib has 17 and has a mark over Wellington.) Last night I tweaked the interactive maps. [1] The result is three-fold: 1) there are bigger circles for places where there are fewer subscribers, 2) there are smaller circles for places like Gmail, and 3) I added markers complete with hover labels listing the domain and number of subscribers. Unfortunately, the markers obscure the circles when viewing the map from the greatest distances. The circles become more apparent once one zooms in. Also, my Geo::IP modules comes with a database, and the database may not be 100% complete. Consequently, not every domain maps to a geo-location. Oh, well. It was fun and informative, even if it is not 100% accurate or usable. [1] interactive maps -- http://bit.ly/hdL55U -- Eric Morgan University of Notre Dame Great Books Survey -- http://bit.ly/auPD9Q

Hi, Eric. While you're at it... what's the percentage overlap between those lists?

Re: [CODE4LIB] geo-locating email domains
Wow, who knew there was such an epicenter of subscribers in Northern California, and that we would eclipse our Southern California colleagues? Maybe we need to hold a regional Code4Lib here in the Bay Area.

Oh, I'm sure there is *a* contingent in the Bay Area. But Roy threw down the gauntlet, saying NorCal was more into Code4lib than SoCal.

Re: [CODE4LIB] geo-locating email domains
For a good time I geo-located the email domains of Code4Lib subscribers, plotted them on a Google map Eric, that is pretty awesome! :-) Disappointed not to show up in there though. The are 6 subscribers with a New Zealand domain, but no mark on the map. (In comparison NGC4Lib has 17 and has a mark over Wellington.) On the bright side, the last time I saw a map of New Zealand covered in those circles was a visualisation of the hundreds of aftershocks in Christchurch, so a little visual peace isn't necessarily a bad thing. :-) Cheers David
