<\/a><\/p>\nThe\u00a0beginning of the References<\/strong> section of the Lie group<\/strong> page looks like this:<\/p>\n You can see that the second reference has an “MR number”, but the first does not. \u00a0At the end of the bibliographic information for Borel’s book, you see MR 1847105<\/ins> and the icon for an external link. \u00a0The “MR<\/a>” is a link to the Wikipedia page for Mathematical Reviews. \u00a0The “1847105<\/a>” is a link to the entry for Borel’s book in MathSciNet. \u00a0So how does that get in there? \u00a0Here comes the messy bit.<\/p>\n If you click [edit]<\/kbd> just after the word “References” at the bottom of the Wikipedia page, a window opens up with a bunch of code in it. \u00a0Wikipedia uses a basic markup language similar to Markdown or HTML. \u00a0They have a page explaining it<\/a>. \u00a0They provide\u00a0information specific to referencing here<\/a>. \u00a0Unfortunately, at the time of this writing, neither of the Wikipedia resources explains how to insert the MR number. \u00a0Moreover, their citation helper (RefToolbar<\/span>)<\/span> doesn’t include this feature, even in the extended version. \u00a0But fortunately,\u00a0\u00a0staring at the page gives you a good idea of the syntax being used. \u00a0Here is the coding for the first two references<\/p>\n If you stare really hard, you will see that the second reference has a piece with “mr=….” in it. \u00a0In fact, it has “mr=1847105”. \u00a0There is nothing similar\u00a0in the first reference. \u00a0So let’s add it!<\/p>\n We pop over to MathSciNet<\/a> and search for the book by Adams. \u00a0Here is what that looks like:<\/p>\n Note that I was lazy and just put in his first initial (with the wildcard operator) and I only put in enough of the title to give me what I hope will be either a unique result or at least a short list.<\/p>\n Not bad – two matches. \u00a0One is the book I want and the other is the Russian translation of the book. \u00a0The full MR number is at the beginning of the listing. \u00a0I have highlighted it in blue here.<\/p>\n Wikipedia, however, only wants the seven digits that come after the MR. \u00a0So I go back to the code in the Wikipedia page I am editing and add this piece of information. \u00a0The syntax is that each field is separated by a vertical bar “|”. \u00a0 Moreover, Wikipedia allows you to insert the field wherever you want in the code for this reference – their system will format it and place it correctly. \u00a0So let’s insert the “mr=0252560” into the referencing code by adding it right at the end:<\/p>\n So, what does it look like on Wikipedia? \u00a0Here it is:<\/p>\n Ta dah! \u00a0We have added an MR number to a Wikipedia reference!<\/p>\n I like it that Wikipedia thinks highly of MathSciNet references, to the point that they make it straightforward\u00a0to add them. \u00a0It would be even better if it was an option in their\u00a0RefToolbar. \u00a0I am not holding my breath, though. \u00a0Sadly, only a tiny fraction of pages on Wikipedia have mathematical citations.<\/p>\n Update (2015.10.07):<\/strong> Wikipedia has some instructions on how to format citations. \u00a0For journals, the help page is here<\/a>. \u00a0For books, the help page is here<\/a>. These pages give you a list of all the acceptable fields (parameters) that you can use in a citation. \u00a0 Also, they use the parameter\u00a0“cite”, where I have used “citation”. \u00a0Both seem to work.<\/p>\n![\"Screen](\"http:\/\/blogs.ams.org\/beyondreviews\/files\/2015\/09\/Screen-Shot-Wikipedia-references.png\")
