I'm at a loss on where to start to look or where to even ask this question. Doesn't seem like it fits what /r/AskHistorians is all about, but it doesn't seem to break any of the rules either.
I'm specifically trying to find the text of a speech given by Otto von Bismarck on September 24th, 1867. All I can find are translated excerpts, and I'm looking for the original German in its totality.
As with much of German research, finding the right Stichwort is key- in this case Bismarcks Reden (Bismarck's speeches). There is a digitized version of a two-volume collection of Bismarck's speeches on the Schleswig issue and includes a 24 September speech. Archive.org also has Fürst Bismarck's gesammelte Reden, although no 24 September 1867 speech. Both of these links are in Fraktur font, as are most German-language documents from this period. Although I rather like reading Fraktur, it does take a while for the eyes to adjust. Yale's School of Music has a useful chart of these fonts which is worth a look if you have not dealt with these fonts before.
