Published by Birkhäuser and the Euler Commission of
Opera Omnia is the definitive printed source for Euler's works. Publication began in 1911, and 76
volumes have been published to date, comprising almost all of Euler's works listed in the Eneström
For those who can afford it, or who have access to it, the Opera Omnia is the best source to
find Euler's works. Not only do his writings appear in neatly typeset, edited form, but each volume also
includes commentaries, some of them very lengthy and very scholarly, on those
of Euler's works in the volume.
In addition to publishing Euler's published works, the Opera Omnia has published
three volumes of Euler's correspondence (see below).
Publication of more of Euler's corresondance and manuscripts is planned by the Opera Omnia
for an unspecified date in the future. Unfortunately, there do not exist even tentative plans to
publish the majority of Euler's letters.
