CTAN has a new package: notes2bib
The notes2bib package defines a new type of note, bibnote, which will always be added to the bibliography. The package allows footnotes and endnotes to be moved into the bibliography in the same way. The package can be used with natbib and biblatex as well as plain LaTeX citations. Both sorted and unsorted bibliography styles are supported.
This package is located at http://tug.ctan.org/tex-archive/macros/latex/contrib/notes2bib . More information is at http://tug.ctan.org/cgi-bin/ctanPackageInformation.py?id=notes2bib (if the package is new it may take a day for that information to appear). We are supported by the TeX Users Group http://www.tug.org . Please join a users group; see http://www.tug.org/usergroups.html .
notes2bib – Integrating notes into the bibliography
The package defines a new type of note, bibnote, which will always be added to the bibliography. The package allows footnotes and endnotes to be moved into the bibliography in the same way. The package can be used with natbib and BibLaTeX as well as plain LaTeX citations. Both sorted and unsorted bibliography styles are supported.
The package uses the LaTeX 3 macros and the associated xpackages bundle. It also makes use of the e-TeX extensions (any post-2005 LaTeX distribution will provide these by default, but users of older systems may need to use an elatex command or equivalent).
The package relies on LaTeX 3 support from the l3kernel and l3packages bundles.
