What is amsrefs?
amsrefs is an extension package for LaTeX that has the following features:
Bibliography style is controlled completely through LaTeX instead of being determined partly by a BibTeX style file and partly through LaTeX.
The same data format is used in the database file and in the LaTeX document.
An amsrefs-format database is a valid LaTeX document that can be printed directly.
An author can send an article with embedded references to a publisher without any loss of internal structural information about the entries.
It is possible to begin using the amsrefs package without abandoning your existing BibTeX database files.
