I am using Zotero to collect and organize all of my citations, which I then export in a bibtex format to use in my LaTeX document, using natbib to make my bibliography. The problem is that I have a couple 'odd' references that do not format correctly. I think this is due to a combination of Zotero not outputting correctly, and my bib style sheet not having the write guidelines for this format. In any case, it does not show the correct formatting (best case), or throws a bunch of errors when compiling (worst case). Since I only have a couple of these instances, rather than tracking down the main problem(s) that cause it, I just wanted to manually format the citation myself. Is there a way to do this? I think I would just prefer to hard-code in the correct text, and then tell LaTeX to print that citation in the correct place (in the reference list at the end) when I reference that source. How can I do this?
