I have a LaTeX document that works fine, but it does give a warning message every time I compile it. Here is the text of the warning message:
LaTeX Warning: Label `' multiply defined.
The name of the label that is multiply defined appears to be an empty string. I am confused about this, but I have had trouble searching for it online because the key element is the empty string, which does not make for a good search term. Does anyone know what this warning message could mean?
I can post details of the document in question as needed, but at this point I have no idea what parts could be important.
Got it. I guess I didn't realize that bibliography items counted as labels - since I never had any intention of referring to them anywhere, I left all of their labels blank initially.
