When you link the page or any resource to your web page which method you prefer to open the page? Are you preferred that new page be opened in a new browser window or in the existing window? In my opinion, if you are linking the page inside your website, always prefer that new page be opened in the same window. And if you are linking the outside resources to your page link, then make sure that the new page should be opened in new window because users may want to look at your list again as they assess the sites they open.
