Like many, I prefer to call these reference notes. For ease of use and brevity I use the standard citekey from Zotero, which I also use to quickly generate bibliographies. Like others have mentioned this is typically the author's sir name and publication date, so something like Gessner1548, or for your particular example Weeks2015. I can then use these quickly as well on cards with quotes or notes relating to sources that get excerpted from them for linking back to them.

Generally I'd caution that if its a topic you're really interested in that you don't do too much note taking from tertiary sources but instead delve into more primary sourcing like the book mentioned in the article by Amy Reading. You'll get a lot further a lot faster, and generally find more useful insight.
