At Equinox, we have about 30 migrations to Evergreen currently scheduled for the rest of the year. We are doing many, we are working with our partner, Alpha-G Consulting, LLC, so that it will be doing migrations, too, with its customers, and, of course, the University of Prince Edward Island blazed yet another migration trail by moving from its legacy system to Evergreen largely on its own and in one month. We have hired our first migration specialist and have developed a number of techniques to cut down the migration time.
Five public libraries and one academic migrated to Evergreen in June. Each migration takes up-front work of data mapping, and finding out what the library wants its installation of Evergreen to do. Then there is a short but intense migration that takes on average two days that is something to behold. One key goal is that there be minimum disruption for the staff and no downtime for the catalog so the migration takes place largely out of sight of the libraries’ users.
US Public library systems running Evergreen
Table 1 (pdf) presents changes in the libraries using Evergreen. The July figure is 51, up 3 from March. The summary data, however, do not show concomitant increases in other data because one’s data are already included in the system it split from and the other, Catoosa County, although it is new to PINES, does not have disaggregated data in the national-level data used here. The increase in the summary figures is for Kent County alone.
The average population served at these libraries is 93,000 which is higher than the U.S. average. However, this fact reflects the result of how PINES is organized: the many small libraries in Georgia are combined into larger systems for resource sharing; and, in turn, this fact reflects on how Evergreen is designed, that is, as a Consortial Library System.
Not just big, but strong
Another interesting figure is that PINES has on several recent occasions had 100,000 circulations per day—a respectable transaction load typical of large systems and institutions. I earlier discussed the nature and effect of the distribution of libraries by size in a Riff on Big and a Riff on Small.
In past analysis of the adoption of open source OPACs, I have found that about one percent of U.S. public libraries are running an open source OPAC. The number of non-PINES libraries adopting Evergreen and their heterogeneous characteristics show that a broad base of libraries has chosen Evergreen and more signing up. We are arriving at the inflection point of open source adoption.
