Easy way to determine towns celebrating 100, 150, and 200 year anniversaries?

Hi, what would be the easiest way of determining what United States towns or cities are celebrating centennials, sesquicentennials, and bicentennials in the next year?

Thanks.

Dunno about “easiest,” but here’s how I’d do it: Chase’s Calendar of Events. The past several years they have published it with a searchable CD-ROM. Find out if your library has a circulating copy that still has the CD, or if they’ll let you borrow the CD out of their reference copy.

Edit: Your library may have even put the CD on their network and provided online access to it. It’s worth checking.

I didn’t even know that existed. I’ll check it out - thanks, KneadToKnow!

Happy to help!
