The best children's library ever!
The Norman Public Library really has the feel of a community center. The children's library has the most wonderful and welcoming librarians, great storytimes, and other activities. I've been going regularly since my 6 year old was a baby, and I've found great activities for him at each age from baby story time, toddler story time, preschool story time, and now the After School Special. There are lots of fun toys for little ones and, of course, lots of books.
My least favorite section is the computer section (though the kids love it). It can be hard to get my four year old to concentrate on something other than the computers. On the other hand, I know many for whom the computers are a plus.
My 64 year old mother has made use of the free computer classes for adults, as well as other programs. They've also got lecture and discussion series, and book clubs. The Norman Public Library is one of my favorite places in Norman!
