Consistency is the most important rule of documentation. The University of Regina Press typically follows the humanities style of documentation according to The Chicago Manual of Style. Please consult with your in-house editor regarding the use of any other documentation styles.
A note about documenting web pages: Because many website addresses consist of long strings of characters which are difficult to retype and because the internet is a constantly changing source of information, we suggest that websites be documented by providing the name of the specific part of the site and institution to which the web page belongs, along with a short URL and the specific date on which you accessed the site. Thus your reference would look like this:
