A polarizing filter will not help you with most artificial light sources. Furthermore, if you are taking the photos in a public place (like a museum), you will have no control over the light sources.
A better solution is to take three image captures from roughly the same distance; one from square straight-on, one from the left at about 75 degrees and one from the right at 75 degrees. Open each image file as a layer in PhotoShop and then align the layers, mask out unwanted reflections, and blend the layers. Usually, the reflections occur at different places on each layer so you can mask out the reflection (or erase it) only on one layer and still have 2 good layers left for blending.
This way, you don't have to worry about the inevitable reflections until you get back to your computer where you can deal with them. Reflections occur not just on glass; a uncovered oil painting can also kick back bright light reflections.
