When a website address is set off by angle brackets, do the Begin and End CBC indicators go inside the angle brackets? That is, since the angle brackets aren't actually typed when going to the website, should the literary angle bracket symbols be used? (dots 56, 236 and 356, 23) <http://web.mit.edu/invent/iow/anderson.html>
You would not include the angle brackets within the CBC indicators for the reasons you stated. They are simply enclosing the computer language. The construction of the angle brackets would depend on the base Code being used (Nemeth or literary for example)
I think I should have explained the situation a bit more. This is for teaching students how to cite Internet sources in reports and "works-cited" pages, and the students are specifically told to use the angle brackets to set off the web site addresses. Does this change things?
No, you would still use a literary angle bracket if your base code is Braille Formats, and a Nemeth angle bracket if the base code is Nemeth. The angle bracket itself is not part of the website address -- it is a grouping sign that will set off the computer language from the rest of the text. So, as you suggested, the begin and end CBC indicators will go inside the angle brackets.
