In the gift of Robert Louis Stevenson mementos just acquired by the Widener Library, an addition of unusual interest and value has been made to what is already one of the most valuable collections of old manuscripts, first editions, personal letters, and relics of great authors in this country. Too little attention is paid by undergraduates to these important and rare collections, which, despite the fact that they are kept in glass cases, are readily accessible for study and inspection by those who are sufficiently interested to take the pains to see them.
