My need is for a simple work flow/usage of Orgmode to annotate and organize existing BibTex *.bib files. I have mentioned on this list that I had found Cb2Bib to work extremely well for, so to speak, harvesting references from Google Scholar. In fact, Pere Constans, developer of Cb2Bib, recently helped me to streamline this usage to allow the use of the "Annotation" field, and I have also worked out a way to output and print a pdf with this field using Cb2Bib's bib2pdf utility. I use this as a basis for library research.
However, I have a wide range of such references in each file, over dozens of topics, and I would like to incorporate by some means an ability to include org-mode subheadings with maybe tags, so enable the citations to be more easily sorted. I do not need to have automatic selection for a bibliography in the output, or automatic insertion of citations, at this point. I have asked this question on this list, and studied from time to time the solutions for using org-mode with bibtex, and visa-versa. I don't really have the time or inclination to learn these. I remember that in BibTeX documentation, was mention that almost anything outside of the individual records could serve as a comment. This is more or less what I have in mind. I would appreciate hearing from anyone who use such a simple approach. It would be most convenient if it were not necessary to change the extension of the *.bib files; I used to do this, but the extra steps for each reference was exhausting. Thank you for any ideas, Alan Davis
