State of Evergreen, June 30, 2011–976 libraries now running Evergreen

This post is an update of Evergreen at 4 to include data on Evergreen libraries through the second quarter of 2011. The first two quarters of the calendar year have been busy ones in the Evergreen community as these summary data show. We are within sight of our 1,000th Evergreen library.

The convention I have used for these tables is to use "Evergreen years," which run from early September (US Labor Day) to the next September. Evergreen first went live in Georgia over the 2006 Labor Day weekend. As a result, the columns headed "EG @ 4" report the summary data on Evergreen’s 4th birthday in 2010. The next column to the right in these tables give the summary data for the state of Evergreen at the end of June in 2011. Hence, there is about 10 months’ experience between the last two columns in these tables and, as the data here show, Evergreen has already had its busiest year—with two months to go to its fifth birthday.

Public libraries are still the dominate type of library running Evergreen but note the change in K12 libraries.

The increase in consortia show that Evergreen continues to be favored by new consortia. Not summarized here is another interesting trend and that the is increasing number of consortia with more than one library type. A few of these consortia are existing multi-types that migrated to Evergreen and several public library consortia have added other types of libraries to their existing Evergreen consortia.

For folks who prefer visual representation of data, may find the second Evergreen Map helpful. It shows migrations in order by go-live date.

Caveats on the counts.

The three tables here have slight changes here or there from earlier versions as a result of new and better information.

These numbers are my current estimates and I have tried to make sure they are as accurate as possible. However, these counts depend on Evergreen libraries making themselves known. Given that Evergreen is open source, it is possible that libraries may not choose to be public. I suspect this to be true in one case; that is, that there is a group of libraries running Evergreen in what might be called "stealth" mode. In another case, the library reports it is running Evergreen but the OPAC is not public. For this report, I include the latter library but for the contest rules, I must be able to see the OPAC to be sure the library is running Evergreen.
