Hello, I made my first edits to the page "Hanseatic League". Could someone please check my work, esp. the citations? I just followed the pattern of existing citations and it seemed to to work fine. Since I am fluent in German, I noticed a citation from a German source which 1) was not entirely accurate, involved some free interpolation and 2) was from a weak online source, the notability of which I would call into question. In any case I can retrieve the core information from an academic source and present it more accurately. Is there some process to follow in order to delete/ replace another edits? Or should I just do it?
