Rara (logico-) mathematica @ www.equivalences.org
As already announced elswhere, now and then, I mean to ``launch'' -- @ my site www.equivalences.org -- a collection / series ``Rara (logico-) math ematica'' [first online, then... we'll see!], containing ``rare'' mathematical and/or logico-mathematical pieces, by different authors, that are either unpublished, so far, or rather difficult to find in our worldwide national and/or academic libraries, or else just inacessible to would-be interested scholars on bare linguistic or other reasons (texts un-available in English or else in other modern language with ``international'' circulation, as, e.g., French, German and the like).
A few examples, cases in point, meant to illustrate the types of texts I have in mind, in chronological order:
 Henry Maurice Sheffer “The General Theory of Notational Relativity”, Harvard University, Cambridge Mass. 1921 [detailed info: https://www.academia.edu/19769172/Witness_Theory_-_Bibliography_Shefferiana_1_equivalences_rara_mathematica_?auto=download]
 Bolesław Sobociński: “Z badań nad teorią dedukcji” [Polish] [Investigations in the theory of deduction], Przegląd filozoficzny, 1932, 35 (3-4), pp. 171--193,
 Grigore Const. Moisil “Recherches sur l'algèbre de la logique” [French], Annales Sci. Univ. Jassy, 22 (1), 1935, pp. 1--118. (This monograph is not included in any one of Moisil's paper-collections already published in Romania, so far.)
 Alonzo Church “Mathematical Logic”, [unpublished] Lecture Notes, Princeton 1935--1936. (The title may be confusing, by the way. This was, actually, a course on [Church's] ``strict'' lambda-delta-calculus, exemplifying also the first ``ordinal logic'' in the sense of Turing [Princeton PhD Diss. 1938]). On this, cf., e.g., my ''Lambda-conversion and Logic', PhD Diss., Utrecht 1981.)
 Corrado Böhm, “Alcune proprietà delle forme beta-eta-normali nel lambda-K-calcolo” [Italian] [Some properties of the beta-eta-normal forms in the lambda-K-calculus], Pubblicazioni del' Istituto per le Applicazioni del Calcolo [IAC], Rome, no. 696, 1968 (19 pp.)
 Nicolaas G. de Bruijn, “Taal en structuur van de wiskunde” [Dutch] [Language and Structure of Mathematics], [unpublished] Lecture Notes, University of Technology, Department of Mathematics and Computing Science, Eindhoven, The Netherlands, Spring Semester 1978 (See also `Euclides', 55, 1979--1980.)
In the above, I mentioned only things I am currently and/or directly interested in. (On -- I can provide further details, on request.) There might be a lot more, of course, as, for instance, Paul Hertz's papers (1924--1935) on logic, some (nearly forgotten) former PhD students and/or collaborators of Hilbert (like, e.g. the Romanian Gabriel Sudan) and so on.
The corresponding editions (to be re-set in [PDF] LaTeX or in [PDF] AMS-TeX) are meant to be equipped with (scholarly) introductions, notes, relevant bibliographies, etc.
On this, I might need a few (or... more!) collaborators. Minimal expertises required: TeX typesetting, basic editorial know-how, and, of course, familiarity with the original language and the subject of the texts to be published. (For instance, ad , I might need a Polish native, conversant in mathematical Polish & English, and already familiar with the mathematical logic jargon of the early thirties, etc.)
(Academic) publishers that might be interested in taking care of this kind of publications (on paper) are certainly welcome! ... [more]
