Martin-Opitz-Bibliothek — Online Catalogue
The Martin-Opitz-Bibliothek provides a public catalogue through Koha. The catalogue is branded with the library’s name, supports search across its collections and displays the Koha home and “Powered by Koha” markers. A current recruitment notice from the library also names Koha among its library-specific systems. The available sources establish the library’s use of Koha; no predecessor or migration date is stated.
