Single or double quotation (speech) marks

The Quick Answer
It is normal to use double quotation marks for a quotation and then to use single quotation marks for any quotations nested therein. (It is permissible to do this the other way around, i.e., use doubles within singles.) Whatever convention you choose, be consistent.
When using quotation marks, it is normal to start with double quotations marks (e.g., "like these"). If quotation marks are then required within that quotation, you should use single quotation marks.

Examples:
  • Anne asked: "Are you really going to see Phantom of the Opera?"
  • The articles states: "A giant squid may have attacked the Marie Celeste as the crew celebrated on the deck."
