On my laptop I use Microsoft Word 2010 in which I am aloud to use non-standard citation styles (see Reference tab, Citations & Bibliography). These styles are XSL Stylesheet files that you can add to the Styles directory which contains the standard styles. Simply adding these new styles to the appropriate directory allowed Word to list them in the Styles drop down list under the Reference tab in Word 2010. However, this does not seem to work on my Surface RT. Only the twelve standard styles are shown, even when multiple new styles are saved into the same directory(ies) as they are. I have located two directories for these styles: 1) C:\Users\user_name\AppData\Roaming\Microsoft\Bibliography\Style and 2) C:\Program Files\Microsoft Office\Office15\Bibliography\Style I am not sure why there are two directories with the same styles, but in either case, adding my other desired styles makes no difference in what Word allows to be utilized. Any help would be greatly appreciated. By the way, I already installed the final version of Office 2013 on the Surface RT.
