Here I share some historical papers/documents/books about polarization optics that are very hard to find and that I consider important or very nice.
Soleillet Thesis (1929) [First description of Stokes-Mueller calculus]
Perrin 1942 (English translation) [First work describing Mueller matrix symmetries]
Mueller 1943 (Memorandum on the polarization optics of the photoelastic shutter] [The most relevant available work by Hans Mueller]
Walker 1904, The analytical theory of light [book] [The only English book that described Stokes parameters way before they were rediscovered]
