I love all branches of the Multnomah Library system, but this one is particularly nice because it is so large and is such a beautiful old building.
Because it is downtown, I don't get there quite as often as I used to, but I try to swing by whenever I an downtown. This library is enormous! You can find books on just about any topic you want and if you have any problems locating anything, the staff members are very nice and helpful.
The only thing negative to mention is that the area tends to attract transients and other types of individuals that loiter on and around the front of the library, so keep that in mind if going alone or going at night. Otherwise, a beautiful location and great library!
