As per the PNAS author guidelines:
References should be cited in numerical order as they appear in text. Because tables and figures will be inserted in the text where first cited, references in these sections should be numbered accordingly. Include the full title for each cited article. All authors (unless there are more than five) should be named in the citation. If there are more than five, list the first author's name followed by et al. Provide volume and issue numbers for journal articles as applicable; provide DOI numbers if volume/issue numbers are not available. Provide inclusive page ranges for journal articles and book chapters. Provide date of access for online sources. Cite databases in the text or as footnotes.
Journal articles are cited as follows:
- Neuhaus J-M, Sitcher L, Meins F, Jr, Boller T (1991) A short C-terminal sequence is necessary and sufficient for the targeting of chitinases to the plant vacuole. Proc Natl Acad Sci USA 88(22):10362-10366.
Because the journal only accepts
.bbl files embedded within the main
.tex file, they do not provide a bibliography style. But their bibliography style has changed over the years (use of colon to separate number/volume and page numbers, volume number not in bold etc.), and there doesn't seem to be any up-to-date bibliography style.
Obviously, this is not the end of the world as I could fix the
.bbl file manually, but I was wondering whether there is a more recent version.
biblatex solutions are both okay, as the
.bbl will be added in the main
.tex file anyway (correct me if I'm wrong on this one please).
Worst-case scenario, how much work would be required to modify the bibliography styles, given that I have never done any work on bibliography styles?
