If you've been published previously, and tell me about it, I look up your book/s.
Which means if you self-published them, I know that and wonder why you didn't say that in the query.
Which means if your first book got six reviews, all of them bad, I see that too.
Which means if your last book was published ten years ago, and you don't have any social media presence, I see that too.
If you've got a less than stellar publishing history,
If that that first book with the terrible reviews isn't indicative of your work today,
Query Under a New Name.
It's not lying.

I am not actively looking for people who need career resuscitation.
I'm not sure any agent is.
