Referring to a Book

Example:
SOMERVILLE, I., 1992, Software engineering. 4th ed., Reading, MA, Addison Wesley.

Special Cases with Books

If there are two or three authors then all should be given

If there are more than three authors then only the first is given followed by et al.

If the book has an editor then ed. is added after the name.

Example:
BOURNER, T. and RACE, P, 1995, How To Win As A Part-Time Student, London, Kogan Page.

For books without individual authors, use the title.

Example:
Turbo Assembler: users' guide version 2.0, 1991, Scotts Valley, CA: Borland.
