R2bib and EndNote2bib read files (respectively in refer and EndNote format) and produces a BibTeX reference list on the standard output.

Since refer files are inherently unstructured, r2bib only does a passable job (for example, it may need to invent a key for an entry, and it has to guess what BibTeX entry type to generate).

EndNote tags may not always match those recognised by EndNote2bib; a further filter program EndNoteTag is provided

See also endnote2bib.
