Resource for journal acceptance rates Does anyone know of a resource or study that compiles statistics about paper acceptance rates in various journals?

I am more interested in biomedical journals, but this would be a good place to list such resources in any scientific field.
A few journals/publishers publish statistics about their acceptance rate, but this data is usually rather sparse, and not communicated on the journal webpage itself.

However, publishers often allow researchers in the fields of scientometrics, ethics or psychology access to their (anonymized) database of paper review/acceptance/publication timelines. You can find papers such as this one (and references therein), which then analyze the raw data and publish some statistics about it. We learn, for example, that the acceptance ratio for Physical Review Letters in 2012 was at 32%.

Other nuggets of information one can gleam include:


  in the Europhysics Letters study Michael Schreiber expressed concern about comparatively high acceptance rates for July-submitted papers


which is always good to know if you happen to work in that field :)
