My advice - there are two types of polarizer filters out there - you will probably be wanting a 'circular polarizer' - it screws on the front of the lens (if you go down that track) - but it can then be rotated on its own plane - to determine how much polarization you want to achieve (polarization works best during the middle parts of the day - due to the way its bends the rays of the sun - they are not very effective at sunrise or sunset for sky effects) unless you want to stop down your shot - they lessen the amount of light entering the camera lens.
If you have a number of lens, and they have different diameter lens - eg. 58mm, 62mm, 72mm etc - I would suggest looking at something like the cokin filter system - it allows you to buy one filter - and use it on all your lens (via lens adapters). If you have a 58mm diameter screw on polarizer and you want to use it on a 62mm lens - you cannot, you would have to buy a new polarizer - this can become expensive.
Also depending upon what lenses you have - be aware that on older lens if after focusing the lens you adjust the polarizer - you may re-adjuct the lens - because the front lens of the camera does not move independantly from the rest of the lens when zooming or focusing, as do most new lenses.

The difference between them is in the way the light rays are organized. A linear polarizer should only be used on cameras without autofocus. A circular polarizer may be used on any camera, but is required for use on an SLR autofocus camera that uses a beam splitter for the light meter and the autofocus sensors.
