Mr. O'Donnell was at the library counter, performing the sort of grim rituals librarians perform with index cards and stumpy pencils and those rubber stamps with columns of rotating numbers. "Ms. Auerbach! What will it be today? Camus? Cervantes?" "Actually I'm looking for a book of poetry by Emily Dickinson" He paused somberly, toying with the twirled tip of his mustache. No matter how seriously librarians are engaged in their work, they are always glad to be interrupted when the theme is books. It makes no difference to them how simple the search is or how behind on time either of you might be running - they consider all queries scrupulously. They love to have their knowledge tested. They lie in wait, they will not be rushed.
