Why is a citation from an e-print missing?
Starting in 2005, we have begun integrating citations obtained from parsing the reference sections of e-prints from the ArXiv. As with references from published papers, there is always the possibility that our procedures may be unable to successfully extract and identify the references. If you think we have missed a citation to your paper from an e-print, you should first check that e-print’s list of references as parsed by ADS to see if your paper is amongst them. If it isn’t, then you can help us by sending us the relevant information as outlined below. For more information, please see our help page on citations.
