Query (advancedsearch): title:(collected works irving langmuir), giving 25 items. Found [web] https://archive.org/details/the-collected-works-of-irving-langmuir-vol.-5 and others: - The full 12-volume set "The Collected Works of Irving Langmuir" (ed. C. Guy Suits, Pergamon, 1960-62), with complete scans and OCR. Several duplicate uploads exist, e.g. "collectedworksof0004drjd" titled "electrical discharge[s]" (1961) and "collectedworksof0003rrja" "thermionic phenomena". - Vol. 5 item (the-collected-works-of-irving-langmuir-vol.-5, 1961) is in the "opensource/community" collection (a user upload, 2021). Files: original PDF 136 MB (292 pages); OCR text "The Collected Works of Irving Langmuir Vol.5_djvu.txt" 657 KB; text PDF 9.5 MB. - [memory, medium] Vol. 5 is titled "Plasma and Oscillations" and reprints the 1928 PNAS paper, Tonks-Langmuir 1929 (both parts), the June 1929 Note and the 1925-26 scattering papers. Its contents were NOT verified this run (the volume subtitle is not in the metadata). - Vol. 2 (collectedworksof0002lang) has "contributions in memoriam, including a complete bibliography of his works". - The copyright status of the 1960-62 Pergamon set is unknown; the item is a community upload. Not downloaded: the owner must approve. Recommended: the djvu.txt (657 KB) of Vol. 5 and of the "electrical discharges" volume, then the page images where equations matter. Bearing: priority 1, the inventor's own work. It is a probably cleaner reprint of the project document, plus the Note (Phys. Rev. 33, 990) and A General Theory of the Plasma of an Arc, which are paywalled at APS.
