Are there any policies regarding bibliographic entries and/or link to online articles?
There are many references circulating along the answers provided in this Q&A website, and I think they will constitute an interesting on-line collection as the site will grow up. Having a standardized way of cross-referencing and citing would be very useful, especially if one is interested in web scraping the site or enhancing his own library of papers.
I usually display the references I found useful to support my answers following standard APA style (or something similar), but what about the many ways of citing/referencing external resources (standard http link, doi reference, etc.)?
