  We present the first English translation of Einstein's original papers
related to the teleparallel ('absolute parallelism', 'distant parallelism' and
the German 'Fernparallelismus' are synonyms) attempt of an unified field theory
of gravitation and electromagnetism. Our collection contains the summarizing
paper in Math. Annal. 102 (1930) pp. 685-697 and 2 reports published in
'Sitzungsberichte der Preussischen Akademie der Wissenschaften' on June 7th,
1928 (pp. 217-221), June 14th, 1928 (pp. 224-227) and a precursor report (July
9th, 1925 pp. 414-419). To ease understanding, literature on tensor analysis is
quoted in the footnotes.
