Gheorghe Tzitzeica - an incomplete bibliography

The aim of this paper is to provide the reader with: the list of scientific papers and books of Gheorghe Tzitzeica; a record with miscellanea papers (in elementary Mathematics, Educational policy, etc); a bibliography with papers quoting Gheorghe Tzitzeica (in the title, in the key words or in the references list). Both the second and third items are inevitably incomplete, as the subject is too vast, the sources are scarce and erodate in time.
