The 1936 BSTJ printing of 'Effect of Electric Shock on the Heart' is a digest of a paper first published in Electrical Engineering, not an original standalone publication

A direct PDF read of the Bell System Technical Journal 15(3) printing of Ferris, King, Spence & Williams's "Effect of Electric Shock on the Heart" shows a footnote the bibliographic record alone does not carry: "Digest of a paper published in the May 1936 issue of Electrical Engineering and presented at the A. I. E. E. Summer Convention, Pasadena, California, June 22-26, [19]36." Electrical Engineering was the house journal of the American Institute of Electrical Engineers (AIEE). This means the BSTJ text most often cited as "the" 1936 paper is a condensed reprint of a work whose first publication was elsewhere, under AIEE rather than Bell System auspices.

The underlying bibliographic facts already on record — title, authorship, venue, pages, date — are unaffected; what changes is what "the paper" picks out. A citation to BSTJ 15(3):455–468 names one authorized rendering of the work, not its point of origin. The original Electrical Engineering printing has not yet been located or compared against the BSTJ digest for omitted material.
