For an adult, this library is great. It's enormous and you can spend hours just wandering around without even starting to look at the actual books.
As a parent of a small child, this library is one of the worst I've been to in NE Ohio. Not that it's horrible, but the Cuyahoga County system libraries put this one to shame (from a kid's perspective). Plus it's a super huge pain to get to the play area with a stroller as you have to enter from the newer building (the older one has no ramp, just many steps), then take the elevator to the tunnel to get to the older building, then another elevator to get to the floor with the children's area.
I'm not saying a library should cater to toddlers, or that it's required to have a sweet play area. I'm just putting this out there so other parents have a heads up. Do not come here and expect your child to be entertained for more than 20 minutes. It will take you longer to get to the play area from the sidewalk than your child will be content to play there.
