If I were a Springer-Verlag Graduate Text in Mathematics, I would be  W.B.R. Lickorish's An Introduction to Knot Theory.

I am an introduction to mathematical Knot Theory; the theory of knots and links of simple closed curves in three-dimensional space. I consist of a selection of topics which graduate students have found to be a successful introduction to the field. Three distinct techniques are employed;  Geometric Topology Manoeuvres, Combinatorics, and Algebraic Topology.
