A centennial commemoration of the Adana massacres was held at Glendale Public Library on 11 October 2009. It was a somber and moving event that held a full house audience for three hours. Present were many descendants of Armenians from Adana, as well as intellectuals and academics. The event was sponsored by Abril Books, Gomidas Institute and Glendale Public Library. The master of ceremonies was Arno Yeretzian.

Garo Moumjian and Ara Sarafian were the main speakers. The audience included other academics, such as Drs. J. Michael Hagopian, Kay Muradian, and Richard Hovannisian and Levon Marashlian.

Both of the main speakers spoke about the horrors of 1909 and the culpability of Ottoman authorities in the killings. In his talk Garo Moumjian discussed the untenable position of Turkish official historiography denying the facts of the 1909 massacres. According to Moumjian, official Turkish historians are weak in their assessment of basic sources related to the 1909 events. According to Moumjian, the Turkish position will have to change.

The event finished with the release of Hagop Terzian's "Cilicia 1909: the Massacre of Armenians" (Gomidas Institute, 2009) and the opening of a special month-long photographic exhibition on Adana 1909 from the Ernst Jackh collection, Columbia University Rare Book and Manuscript Library.
