At your fingertips is this amazing wealth of resources. The Richland Public Library is family-oriented, offering children's storytimes (where they dance, sing, play with bean bags, do fingerplays) and of course read! They have art displays, family events with entertainment and more. There is a whole row of computers with internet access. Slides, newspapers, magazine, archives. Quiet rooms that you can sign up for for study groups or meetings or whatnot.
The staff are always helpful in pointing you in the right direction. There's been plenty of times I was unsure where to begin searching but always come away with info I need.
