Bread crumbs is a weird name for the trail of links that show where you are.  An example is on the left on this page.  Our bread crumbs are based on the structure of the website.  That is, they tell you where you are based on how the website is organized.  They don't necessarily tell you where you are based on where you've been.  If you want to retrace your steps, use the back button or back arrow of the browser you are using.  But if you want to know where you are relative to everything else on this site, look to the crumbs.
