The perspective of English as an International Language (EIL) has been proposed mainly to alleviate the tenets of language and cultural imperialism and, of course, to facilitate communication through different varieties of English. Hence, English language classrooms are the preliminary venue for the inception of such a rudimentary movement. Bearing this in mind, in this study, we evaluated a number of recently published English textbooks, "World English," "Top Notch" and "American English File" as supplementary resources in language teaching and learning. In so doing, adopting a schema-based viewpoint, computer files of the reading texts of the books were created, and their single and phrasal words or schemata were categorised into the three domains, semantic, syntactic and parasyntactic. In order to investigate the cultural load of each single schema and to find to what extent the EIL paradigm has been framed within the textbooks, Kachru's (1992) division of inner, outer, and expanding circles was employed. The overall results revealed that, although these textbooks aimed to address the language learners anywhere in the world, their references to the inner circle countries and native speakers of English still surpass the outer and expanding circle countries.
