Libraries are becoming community centers around here - because of the service as Jane mention, also because Medicare, Social Security, Job Centers, etc., are urging and in some cases requiring people to access them over the internet or phone. In our area, low income persons are getting ride of their land line phones and turning to cell phones with limited minutes, so they cannot afford to sit on hold for an hour to apply for benefits. The library computers are in big demand. Also, libraries here have job training and job hunting materials and computer programs to help people update their skills.
What amazes me is the number of persons using the reading room (newspapers and magazines) and prowling the stacks. All ages.
