As you walk through the city of Palanthas, your stopped by a man who diverts your atention towards a library, and starts to talk...
"Welcome to The Not so Great Library of Palanthas (in other words, this is a public library). But, that don't mean that there is not great information within, so please, come in. Don't be shy."

You can either enter the library, or see if there is another place open at this hour.
