  In this review we attempt to present an overview of some of the better known
quantization techniques found in the current literature and used both by
physicists and mathematicians. The treatment is more descriptive than rigorous,
for we aim to reach both physicists and mathematicians, including
non-specialists in the field. It is our hope that an overview such as this will
put into perspective the relative successes as well as shortcomings of the
various techniques that have been developed and, besides delineating their
usefulness in understanding the nature of the quantum regime, will also
demonstrate the mathematical richness of the attendant structures.
