There aren't a ton of exhaustive, earnest guidebooks to Poland. Maybe that's because when I needed one, I was living in Prague, and I couldn't readily get my hands on English language guide books to the next country to the east. Fair enough. But I think this one (left to me by a friend moving back home) is pretty good. There are tons and tons of towns listed in here -- if there's a place in Poland you want to go, then there's probably information on it in here. They do top lists, which is a good way to narrow in on something rather than getting overwhelmed. And it CAN overwhelm, or in some cases, with the smaller towns, it can can occasionally underwhelm. But no matter. It's just nice to have something to rely on, and you can do that with this book/series.
