" Buy books, then, that you have read with profit and pleasure and hope to read and reread. Buy books that you may underscore passages and write upon the margins, thus assuring yourself that the book is your own. Keep the books that mean the most to you close at hand, one or two, if possible, on a table at your bedside. Do not hide away your favorite books or keep them locked in enclosed shelves. Do not keep them under glass. "
