My reaction to that sentence in a query letter is not what you hope it will be when you write it. You hope it implies "experienced author with pub credit who has a sales record."
What I infer from it is "book that sold fewer than 200 copies and means author can't be listed as a debut novelist."
Lest you think I'm making up the sold fewer statistic, here's a recent post at How Publishing Really Works blog that elaborates on that. It's drawn from a longer post at Writer Beware on the topic of POD.
When you write a query letter, you want everything in it to be persuasive. An AuthorHouse/iUniverse book is not persuasive. If you've had a book printed there, leave it out of your query letter.
