Hi Jochen

Thanks a lot for these suggestions. However, I hesitate to put these
changes into bibtex.el. It appears to me that the above value for
bibtex-generate-url-list reflect your personal preferences so that
they should go into the personal .emacs:

- The default values for user variables in bibtex.el reflect the
  usage of BibTeX as a bibliography database for LaTeX documents. To
  the best of my knowledge, neither URLs nor DOIs are required for
  LaTeX documents.

  The default value for bibtex-generate-url-list is an example for
  how to use this variable.

- The buttons for URLs in BibTeX files are inserted via font-lock.
  The algorithm is fairly complicated. I expect that a long list of
  schemes in bibtex-generate-url-list can make font-locking rather
  slow if one has a slow computer and/or a large BibTeX file.
  (Comments welcome! I can't check that on my computer, it's pretty
  fast.)

  On the other hand, the algorithm is fully customizable. If the
  journals you work with support DOIs, you can add a DOI field to
  bibtex-user-optional-fields. And the above value for
  bibtex-generate-url-list will generate buttons for these fields.

  Let me know if there is anything that cannot be done by
  appropriate values for bibtex-user-optional-fields and
  bibtex-generate-url-list.

- It seems to me that your choice of journals from AIP reflects your
  personal preferences. See http://link.aip.org/jhtml/rre_list.jsp
  for a more complete list of AIP journals. However, this rather
  long list of journal names would make font-locking even slower.
  (The British IOP and the European EPS use similar schemes for
  their journals.)

  In my .emacs, I have pretty much the same value for
  bibtex-generate-url-list you suggest. (I expect that you are a
  physicist like me. You are interested in the same journals.)
