hiding between the covers of a book

“A library is a good place to go when you feel unhappy, for there, in a book, you may find encouragement and comfort. A library is a good place to go when you feel bewildered or undecided, for there, in a book, you may have your question answered. Books are good company, in sad times and happy times, for books are people - people who have managed to stay alive by hiding between the covers of a book."

[Letters of Note; Troy (MI, USA) Public Library, 1971]”
