Until I started surfing the Internet several years ago, I thought my name was unique. I was wrong.
The author of Hey, We Can Play This Game shares my name but isn't me, nor am I Michael B. Bracken, the author or co-author of several books such as Perinatal Epidemiology. There's also a Mike* Bracken out there who reviews horror movies and may be the same Mike Bracken who was the horror expert on the game show Beat the Geeks, and recently another writer named Michael Bracken--perhaps one already mentioned--has had quite a bit of his non-fiction appear in Google searches for my name.
I wonder how much identical or nearly identical bylines impacts our writing careers. Might editors purchase something from one of us thinking we're another one? Might a reader purchase a book from one of us expecting the work of another?
Then again, maybe one of us needs to become really, really famous before I concern myself with the answers to these questions.
*FYI I'm not "Mike."
