In Turkey, since 1948, the auxiliary resource books used in teachings of History of Islamic Arts and Architecture studies in higher education are the ones, prepared through summarised translations from certain European authors’ publications. The contents of these books provide very little information and visuals on important buildings of Early Muslim Architecture. In addition, the information given from the works of those authors on these buildings are conveyed as the only and the most accurate available in the market, without mentioning anything about the existence of alternative views of other researchers. Although K.A.C. Creswell presented substantial alternative information in his book titled Early Muslim Architecture which he revised and published as two volumes (three books) in 1969, but the valuable information he presented were not incorporated in the Turkish supplementary books. Insufficient information and visual materials in sources of Early Muslim Architecture sources in Turkiye, are analyzed in comparison to K.A.C. Creswell’s aforamentioned publicatiıns in this research article. Further more, it will be demonstrated that Creswell’s books contain a substantial amount of information and visual materials, sufficient to address many of the deficiencies present in Turkish educational resources.
