What is meta? ×
Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 144 Stack Exchange communities.

The number of scientific Stack Exchange sites is increasing steadily currently we have for the natural sciences: Statistical Analysis, Math, Theoretical Computer Science, Physics, Skeptics, Astronomy, Theoretical Physics, Computational Science, Biology and Cognitive Sciences.

One feature that would be useful to all of these sites would be making it easier to cite scientific literature.

A proper citation of a scientific paper to support your answer would look roughly like this

According to Nikolova et al.1 DNA can form transient Hogsteen base pairs ...


DNA can form transient Hogsteen base pairs (Nikolova et al. 2011) ...

All citations would be listed at the end of the post and if available the citation in the text itself as well as the full citation in the list would be linked to an online source of the reference, preferably via DOI to avoid link-rot.

Of course it is already possible to achieve this effect manually, but it is a lot of work to properly format the citation in markdown. It would be very nice if the citation could be generated automatically from a BibTeX or RIS file, those are usually available directly on the online version of the scientific article, or can be easily exported from a citation management software.

Another way to get the bibliographic data for papers form the life sciences would be the Pubmed database.

My idea is that this would not only make it easier to add proper looking citations, making the sites look more professional as a whole. but that it would also increase the expectation in regards to citations. It should encourage users to back up their claims with primary literature and improve the quality of the answers.

Ideally this would work by just copying a link from the journal homepage or a database like Pubmed, and the citation data would be automatically fetched and inserted into the post. Some citation software like Zotero is already able to do that, so this might be possible by integrating an existing library.

An additional idea would be to use the citation data for the "Linked" or "Related" block in the sidebar. Posts that cite the same sources (determined e.g. by comparison of the DOIs) are usually about closely related topics, and making it easier to find them might be very useful in some cases.

I support this; I would also support a watered-down version of it (sans the bibliographic stuff) on Stack Overflow, but I guess that would be a separate feature request –  Pëkka Dec 18 '11 at 20:48
If you could make a system where citing academic sources wasn't a pain in the butt you'd be a billionaire, especially if you could do it in a little text web editor instead of a dedicated software suite like EndNote. I don't see a simple way to work it in. –  Ben Brocka Dec 24 '11 at 2:57
... the Science of Skeptics? –  Steven Jeuris Feb 22 '12 at 12:44
@StevenJeuris Skeptics is not explicitly a science site, but a lot of questions on it are about science. The site also requires references for every answer, so support for citations would be very useful there. –  Mad Scientist Feb 22 '12 at 12:48
I was being sarcastic. ;p It just looked strange in that list. ;p –  Steven Jeuris Feb 22 '12 at 12:49
As I'm now part of Cog Sci.SE I'm seeing the importance of this, but still can't think of a great solution to add to our current markdown set up... –  Ben Brocka Feb 22 '12 at 14:14
+1 +1 +1 +1 +1 +1 +1... citation is the biggest turnoff of proper referencing. Making it easy gets people to give more references, which is good. –  Armatus Jun 18 '12 at 22:59

I'll sketch an example of how I think an initial version of this feature could work. For the areas I'm interested in, pretty much every journal is indexed in PubMed, this would cover the whole life sciences, biology, medicine and chemistry.

My idea would be to add a way to automatically generate a citation from a DOI or a Pubmed ID. Those two identifiers are readily available and can easily be copied from a Pubmed search result or the journal homepage.

Pubmed provides a webservice to query their database.

To get the Pubmed ID from a DOI, you can use the search and supply the DOI with [AID] directly behind to indicate that you only want to search the identifiers:


With the Pubmed ID you can query the full bibliographic information in various formats the following way:




There is also a gateway that provides the data in JSONP format that would be useable in a user script: http://entrezajax.appspot.com/developer.html

From this data a citation looking something like the following should be generated:

Schlappa, J. et al. Spin-orbital separation in the quasi-one-dimensional Mott insulator Sr2CuO3. Nature 485, 82–85 (2012).

For this example I used Zotero with the Nature citation style. Ideally the citation should be properly formatted and linked to its DOI, as already shown in the example in this question.

To create these citations a library like citeproc-js might be useful.

This would make it far faster and easier to cite scientific articles, encouraging users to back up their answers with primary literature, making posts that use the feature look more professional and by using the DOI safeguard those links against link-rot.

It's worth pointing out that not all publishers expose the DOI to non-subscribers. JSTOR.org for example has recently redesigned to hide citation information from those without journal access. I think this solution would need to have the ability to add the citation details and link manually, not only relying on identifiers like DOI or PubmedID –  Richard Smith-Unna Jun 16 '12 at 11:09

An interim step could be to use something like HEVEA. The editing would have to be done elsewhere with html pasted here. Below is the body of the html file generated from bibtex.tex. The result didn't work out as nicely as I had hoped with the styles removed. There is a citation link in there, but it doesn't reference correctly.

This is a citation of a very [1] important work.


[1] Author, etc. This document was translated from LATEX by HEVEA.
