Apologies in advance for the rudimentary question. I’ve noticed different scholars using “fr.” and “F” as abbreviations for fragments. Are there conventions for which to use for which ancient authors/types of fragments, or is it a matter of picking one and staying consistent? In the case of “F” how do you make it plural (for “fr.” I’ve seen “frr.”)?
I understand that fr. and frr. are standard, but I’m still not entirely sure when to use F or why some scholars choose to use F instead of fr.
For instance, it seems that the FGrHist consistently uses F, never fr. So when I reference a fragment that I found in FGrHist do I need to use F instead of fr. when I refer to the fragment?
A quick follow up:
For Diels-Kranz it seems like fragments are never referred to with fr. or F, but simply (e.g.) DK 11A9… I wonder why not using fr. became the convention of the presocratic fragments…
