I have grouped together the four subdivisions of Coppenrath because there isn't a lot to say about each individually. I have not translated the German Wikipedia's comment that Coppenrath Verlag is best known for scientific publications as I can find no evidence this is true. I have updated the number of Lino-Buecher but cannot offer any better source than a bookseller (I'm not sure if I'm allowed to use book-sellers' sales sites as sources, so I haven't put one in). The German Wikipedia is unsurprisingly out of date on the total number, as I find I can currently buy No. 66. Elemimele (talk) 23:12, 19 December 2022 (UTC)Reply
