How can I find a certain cute little poem about a guy named Bill ?

I found it 57 years ago in a then new set of Britannica Encyclopedias. I never could find it back and used the set of books later as a down payment on a used car. lol ~~The poem was about, "some people call me William, Willie or Will and others call me Bill or I go by just Bill."~~ Have any of you ever seen this little poem or can you track it down for me ? I'm not familiar with how to search. Thanks
