2 Timothy 4:13 Cloak = A large sleeveless outer garment made of a single piece of heavey maerial with a hole in the middle through which the head was passed. It was ued for proection against cold and rain, particularly in traveling. It may be that Paul felt the need of it because winter was at hand and his dngeon was old (Kelly). The books = biblia, Parchment = pergamena. The word denotes a piece of skin or vellum pepared for writing purposes. Paul may have been refering to OT scriptures, or other written documents, or materials on which he could write to others. See the ISBE for good info on cloak, books and "parchments" and the fact that he was probably arrested at Troas and hurried off to Rome so fast he didn't have time to collect his personal possessions.
