Balliol College.
He was elected Fellow of Oriel College in 1600, and received his Master of Arts 27 March 1604. On 9 May 1620 he was chosen chief librarian of the Bodleian Library, a post he discharged with great vigour and acumen until his death. At that time he occupied "Cambye"s lodgings", also written "Camby"s", once a part of Saint Frideswide"s Priory as a medieval tenement.
He afterwards sold the property to Pembroke College, as a residence for the master.
Rouse annotated a collection of Robert Burton’s books which were given to the Bodleian Library by testamentary disposition on Burton’s death, and two of his inscriptions are cited by Alan H.Nelson as supplying independent confirmation that, for this learned bibliographer, William Shakespeare was identified by a contemporary as the author of Burton’s copies of two of Shakespeare's narrative poems. The inscriptions read.
Venus and Adonis by Wm Shakespear London 1602
The rape of Lucrece by Wm Shakespear Imp{er}fet.
To this circumstance we owe Milton"s mock-heroic ode To John Rouse (dated 23 January 1646-1647) inserted in a second copy, preserved at the Bodleian.
In 1645 he refused to lend King Charles the "Histoire Universelle du Sieur d"Aubigné" because the statutes forbade the removal of such a book Christopher Arnold, professor of history at Nuremberg, and Lambecius both complimented him. He died on 3 April 1652, and was buried in Oriel College Chapel.
Rouse wrote a dedicatory preface to a collection of verses addressed to the Danish proconsul, Johan Cirenberg (Oxford, 1631).
He also issued an appendix to the Bodleian Catalogue in 1635. His portrait hangs in the Middle Common Room of Oriel College.
