What can a library do when people are cold, tired, hungry, and scared? The library brings them all the things it always does. It provides information, such as FEMA applications, where aid centers are set up, locations for Red Cross and Doctors Without Borders. It provides comfort: charge your cell phone, send an email, or just get out of the cold for a few minutes. It provides entertainment: books were lent whether people had a library card or not.
These are all the direct benefits, but there are many intangibles as well. Everyone knew that, even at their lowest point, the library was still there for them.
