We would like to extend our thanks to the General Directorate of Cultural Assets and Museums, and especially to Director General Nadir Avci, Assistant Director General Ilhan Kaymaz as well as to Çigdem Morçöz and Songul Erbay for their strong support and good advice. Particular thanks are due to representatives Ahmet Beyazlar from the Gaziantep Museum in the spring season and to Cumhur Sal from the General Directorate for the summer. The Acting Director of the Yozgat Museum, Mehmet Ayar, and Assistant Hasan Senyurt have as usual been most supportive and their cooperation has been greatly appreciated.

We would also like to thank the Governor of Yozgat, Vali Gökhan Sözer, the Director of the Department of Rural Services, Muharrem Sengül, the Director of TEDAS, Bülent Gürel and the Director of Türk Telekom, Resul Aydin, and their staff in Yozgat and Sorgun, for great improvements to the road and to the village infrastructure and services. The Sorgun District Governor, Kaymakam Meftun Dalli, and the Sorgun Mayor, Belediye Baskan Ahmet Simsek, have provided help and assistance essential to the work progress.

The main sponsors of the archaeological research in 2004 were Lafarge Saglik Egitim ve Kültür Vakfi, The Loeb Classical Library Foundation, The Oriental Institute of the University of Chicago, The Joukowsky Family Foundation, The Anatolian Archaeology Research Foundation, John Kelly Consulting Inc., The Charlotte Bonham Carter Trust and anonymous donors. The British Institute of Archaeology at Ankara made a grant towards the cost of the site guard and preparation of publications, the latter also sponsored by the Anglo-Turkish Society. Life in the field was made more comfortable thanks to The Ankara Hilton, The British Embassy, MNG, Onduline and Yibitas Yozgat Çimento / Yibitas Lafarge. Sokkia-Seza loaned surveying equipment. ESRI, ERDAS, Islem and Geoscan helped with software and Datasel, Eternal/Hizli and Romar with hardware. Research activities, including those related to the Eco-Center, are supported by funds from AKG, The Australian Embassy, The Canadian Embassy, Erdogan Akdag, MESA and Yenigün, channelled through the METU Development Foundation. METU Computer Center provides technical support and METU Press assists with publication.

At METU, staff and students from the Faculty of Architecture and the Settlement Archaeology and Archaeometry Graduate Programs are involved in various aspects of the Kerkenes Project including the environmental studies focusing on the Kerkenes Eco-Center programme of activities. The project has also ongoing programs of collaboration with the METU Museum, TAÇDAM, GGIT, the Department of Geological Engineering and the Department of Metallurgical Engineering. The Computer Center continues to provide technical support and particular thanks are due to Ibrahim Çalisir for his patience in dealing with old computers. We are extremely grateful to the Office of the Rector for providing office space for the Kerkenes Project to replace the project office no more available in the Faculty of Architecture.

Collaboration outside METU includes SUNY Buffalo, the Oriental Institute of Chicago University, the Malcolm and Carolyn Wiener Laboratory for Aegean and Near Eastern Dendrochronology at Cornell University, the Department of Near Eastern Studies of the University of California at Berkeley, Laboratoire de Géographie Physique of the CNRS and the Department of Hydrogeology at Hacettepe University. We would like to thank David Stronach, Prof. of Near Eastern Archaeology at Berkeley, for his continuing support beyond his formal involvement with the Kerkenes Project

In the spring season Nurdan Çayirezmez was Acting Director at times when the Director was in Ankara, while Scott Branting took charge for part of the summer when the Director had to take leave of absence for personal reasons. In addition to the authors the team comprised conservator Noël Siver, illustrator Judith Sellers, publication assistant Isabelle Ruben, registrar Catherine Draycott, archaeologist Nurdan Çayirezmez, trench supervisors Andreé Bojalil, Tasha Granger and Tuna Kalaycı, assistant supervisors Ruth Bordoli, Melissa Clissold, Piraye Hacigüzeller and Natalie Summers and students Maria Kelly, Seher Sencer and Derya Ulusoy. Evangelia Ioannidou will study the bones at METU. Pamela Summers and Bediha Gençarslan ran the kitchen for most of the season while Harun Muratdagi assisted with administration. Muhtar Osman Muratdagi used his minibus to ferry workmen and do expedition shopping. Memis Gençarslan continues to be the site and house guard and workmen were employed from Sahmuratli Village to take part in resistivity survey in the spring and excavation in the summer.

Efforts to establish the Kerkenes Eco-Center, in the village of Sahmuratli (Fig. 4), are continuing and the expedition base proves to be a very appropriate vehicle to convey the importance of a sustainable and environmentally friendly approach to our daily life and needs. Following the initiation of the first activities by grants from the Direct Aid Programme of the Australian Embassy and MESA, The Canada Fund has generously supported the 2004 programme focusing on activities which will help the establishment of the newly formed Village Association and bring new life to rural areas. The strawbale construction, arousing the curiosity of many visitors, and the brick press from Parry Associate (UK), donated by the Burdens Charitable Foundation in Manchester, have demonstrated the potential impact of the ongoing environmental studies research. The British Council Partnership scheme continues to permit collaboration between colleagues from the Department of Architecture at METU and the Architectural Association in London for further research in this field.

The Kerkenes web page is now divided into three parts:
• K-One, covering the initial ten seasons of research and which continues to be updated;
• K-Two, concerning developments from 2002 onwards;
• K-Eco reporting on the development of the Kerkenes Eco-Center and associated environmental studies.

Annual reports and details of sponsors and participants can be accessed with the new shortened web address which opens the Kerkenes Homepage with the three links.
