Many bibliography databases supply a DOI (Digital Object Identifier) or arXiv eprint number with BibTeX entries. However, the standard BiBTeX style files either ignore this information or print it without hyperlinking it correctly. Here’s how you can get working clickable links to both DOI and arXiv eprints.

For the new style arXiv identifiers (April 2007 and onwards) we recommend these bib-style extensions: **archivePrefix = "arXiv"**, **eprint = "0707.3168"**, **primaryClass = "hep-th"**,

In order to use this entry properly the macro \mnras must be defined in your document and it must give the correct replacement text.

If the RRID is well-formed, and if the lookup found the right record, a human validator tags it a valid RRID — one that can now be associated mechanically with occurrences of the same resource in other contexts. If the RRID is not well-formed, or if the lookup fails to find the right record, a human validator tags the annotation as an exception and can discuss with others how to handle it. If an RRID is just missing, the validator notes that with another kind of exception tag.
