Of course, if you read something like See [1] and [2,4] for background and recent developments. that's terrible. However, if the author cares at all, (s)he would have written: See the textbook by Foo [1] and the recent papers by Harry and John [2,4] for background and recent developments.

So, part of the truth is as follows (see http://www.findstat.org/StatisticsDatabase/St000575 or http://www.findstat.org/StatisticsDatabase/St000319 for examples * Alice submits a statistic using http://www.findstat.org/StatisticsDatabase/NewStatistic, and in the reference field, she is (strongly) encouraged to type something like [[MathSciNet:3338726]] [[arXiv:1304.4309]] * FindStat retrieves bibtex from the mathscinet and arxiv catalogues and checks that they indeed refer to the same paper (by definition: authors and title must match). The identifier from the most preferred catalogue is then used as bibtex key in our bibtex file. If somebody references this paper again, the bibtex file will not be modified. Within a statistic entry, the references are simply numbered [1], [2], [3], ... Currently, there is no automatic linking between numbers used in the description field of the statistic and the list of references. In this case, I think it would be overkill. * in case Alice did not use an identifier but rather free text, FindStat sends this to http://www.ams.org/mathscinet-mref and tries to obtain an MR number. Failing that, the reference is left as Alice types it. * On the webpage, we show then author, title, and identifiers. I would have suggested to write "As shown by Chern et al. [[MathSciNet:3338726]] one can do this at that" because it works for me (I also use this in my LaTeX files, using reftex), but I also admit that I do not care enough to advertise it more :-) The main advantage is that one then has automatically unique identifiers, which can (but need not) be transformed easily into whatever you want for the end user (eg., the one reading docstrings).
