Q. In a story where the last text provides an URL, website, or e-mail address, should it not have a period at the end? I find sometimes clicking on the URL it does not take one directly to the displayed location if a period follows.
A. Yes, you must put a period at the end of a sentence, even if the sentence ends with a URL (or e-mail address). If it’s essential that the link be clickable, make sure that the code that determines the hyperlink destination does not include the final period. (Most word-processing programs allow you to edit hyperlinks, even if they’ve been created automatically.) If you don’t have that option, then consider moving the URL so that it doesn’t fall at the end of a sentence or anywhere else that punctuation might be required.
