Books with more than one author
Include the names of all authors in the reference as they are written on the title page. If there are two authors, the names should be separated by 'and', if there are three, by a comma between the first two and 'and' between the second. If there are more than three authors, then only include the name of the first, followed by 'and others', (not et al).
If the authors share a surname, write out the names in full to avoid confusion e.g. 'John Brown and David Brown' not 'John and David Brown'. A reader could be misled in to believing the surname of the first author had been omitted.
