I have just posted at https://archive.org/details/agad_fond350_sygnatura168 photographs of a book of 1764-1766 Jewish censuses for the following towns (+ some nearby villages), which I wrote about here in 2018:
Kingdom of Poland: Baranów (Lublin), Końskowola (Lublin) + Wlostowice, Międzyrzec Podlaski (Siedlce), Staszów (Radom)
Galicia: Berezhany / Brzeżany, Jarosław, Kalush / Kałusz, Narayiv / Narajów, Peremyshlyany / Przemyślany, Sieniawa, Skole, Tarnoruda
Podolia: Hraniv / Granów, Letychiv / Latyczów, Medzhybizh / Międzybóż, Nikolayev / Mikołajów, Sataniv / Satanów (statistics only), Stara Sinyava / Stara Sieniawa
Volhynia: Klevan / Klewań
I photographed the book at AGAD in Warsaw and have received written confirmation from AGAD that this material is in the public domain and can be shared as long as a citation is given to the archive and file location.
Example citation: Archiwum Główne Akt Dawnych w Warszawie, Fond 350 (Archiwum Potockich z Łańcuta), Sygnatura 168.
More details are given at the link above, including a table of contents with links to jump to the first images for each town.
Anyone is free to index this material, but, if you are interested in doing so, you might want to first 1) announce your intentions here to avoid duplication of effort and 2) reach out to the appropriate Research Directors or Town Leaders at JewishGen, Gesher Galicia, or JRI-Poland. It is my understanding that Staszów and Międzyrzec Podlaski have been indexed but are not yet online. I do not plan to organize indexing myself.
Also, anyone who would like to share/post some or all of these images elsewhere is welcome to do so -- just include the citation.
Please note that I am not affiliated with archive.org and am not responsible for other content hosted there, I am just using it to share and preserve public images as do the U.S. Holocaust Memorial Museum, Leo Baeck Institute, Library of Congress, Reclaim the Records, etc. In the future, I may post additional archival documents there (with permission from the archives), of both Jewish and more general genealogical interest.
Thanks very much to AGAD and its archivists and supporters for preserving this important material and making it available to researchers.
