Suggestion: field for references to used sources of information

From time to time, articles on Habrahabr are very similar to those already existing in the expanses of a large network. Compiling information from open sources is good, but in this case I would really like to know where exactly this information is collected (especially if parts of the text are copied one to one from the original).

And therefore, there is a suggestion - you need to make an additional optional field on the page for creating a new topic. And let it be the field " links to sources ." This decision will help us to instill in ourselves a culture of “referring”.
