[Koha] Big Koha Migration of Turkey

[Marshall Breeding]

Thanks to data provided by Mengü, these libraries are now represented in libraries.org:

http://librarytechnology.org/libraries/search.pl?ILS=Koha%20--%20Devinim

http://librarytechnology.org/map.pl?ILS=Koha%20--%20Devinim

and the global map:
 http://librarytechnology.org/map.pl?ILS=Koha

Any additional help in making this resource more comprehensive for libraries using Koha is much appreciated.
