Source for identifying bulbs?

Is anyone available of a source for identifying bulbs?

I was given 4 unidentified bulbs - they are alittle bit larger than the size of a golf ball, they have a brown papery cover, and lateral bud growth.

I am new to bulbs, so any help would be appreciated!

You can compare with some of the bulbs in this chart. I think the best thing is to post a picture here or in the Identification forum.
Good luck
