I hope this Dictionary will satisfy the demanding reader and researcher, thanks to the wealth of entries (99,940).

After years of effort and research, I gathered this material by consulting many dictionaries of foreign and Greek geographers, historical researchers, and especially all the ancient Greek authors (1,500 volumes), as well as foreign universities, such as the Geographical Encyclopedia of the University of Heidelberg, which consists of 87 volumes, each volume having 1,450 pages.

This enormous work of the Academy took 300 years to compile and is still ongoing. This was the reason I began the research and writing of this dictionary.

Also, in the USA there are 50 university departments that collect information from all the universities of the world, record it, and gradually present it on the Internet, such as the 13,000,000 place names found in this department. The University of Oxford in England, from time to time, presents similar research.
