If you use Google Scholar to provide your references, double check them to make sure they are correct. It can be tempting to copy/paste the citations directly in a crunch. But nothing is more embarrasing/insulting/damaging than misrepresenting an author and their work.

De Boor, C. (1978). A practical guide to splines (Vol. 27, p. 325). New York: Springer-Verlag.
