+** sci-id
+index:orcid [[index:researcher id]]
+
+#+BEGIN_SRC emacs-lisp
+(require 'sci-id)
+#+END_SRC
+
+This package just defines two new org-mode links for http://www.orcid.org, and http://www.researcherid.com. Here are two examples:

+
+If you find you need to convert some bibliographies in some format into bibtex, this library is a starting point. This code is mostly wrappers around the command line utilities at http://sourceforge.net/p/bibutils/home/Bibutils. I thankfully have not had to use this often, but it is here when I need it again.

+- ris2bib :: Convert an RIS file to a bibtex file.
+- medxml2bib :: Convert Pubmed XML to bibtex.
+- clean-entries :: Map over a converted bibtex file and "clean it".
