How do I link to a scientific article? I want to link to a scientific article (actually so I can ask a question on another SE site) and I was wondering what is the proper way of doing so? I know going around a paywall is illegal and I don't want to do anything like that?

So what is the proper way to link to an article so that I may ask a question about it?

How do I maximize access to it? For example, I'm seeing the article behind Paywall A, but another user has access to Paywall B (where the article may also be available, but would obviously have different link.)
The most straightforward way is to provide a regular scientific citation. The users can then use their individual library or online service to access the article.

Alternatively, you could just provide a link to the most canonical location. Even if the reader can't access the article, he or she will find the bibliographical details there as well. (Thanks for this suggestion in the comments.)
