  Having been an editor for Physics Letters B (PLB) for many years I became
interested in the history of publishing, especially in particle physics (HEP).
Since PLB goes back to 1967 and an index of all PLB publications is available
online, this information was used to look at the history of PLB publications
over time. It should be noted that PLB publishes new results in particle
physics or high energy physics, nuclear physics and also in astrophysics and
cosmology. This is the start of an effort to look at all publishers that
publish research from HEP.
