Are there methods or tools to facilitate generating bibliographic data files (for BibTeX, EndNote, RefMan, etc.) from database records to show to visitors of a website so they can easily import the citations?
A powerful tool to convert between various bibliographic formats is bibutils. EndNote and RefMan should both readily accept the RIS format.
On a Linux system you can execute
cat myrisfile.ris | ris2xml | xml2bib > mybibfile.bib
to convert myrisfile.ris to mybibfile.bib in a BibTeX format if the package bibutils is installed.
