One of the perquisites of the scholarly profession is the gradual leave-taking of our friends and colleagues which eases the pain of good-by. Despite the approximate conjunction of Hajo Holborn's death with the completion of his great History of Modern Germany, a conjunction which seemed to seal the finality of the abrupt stillness, he actually had in hand several lines of unfinished business which will keep his inimitable and indispensable historical spirit with us still during the coming months. These enterprises, which represented Hajo Holborn's integration of the variegated concerns in his wide-ranging career and his definitive settling of accounts with them, included two kinds of projects: on the one hand, collections and editions of his own writings and, on the other, interpretive essays prefacing new editions of other historians and of their historical works on themes with which he had long associated himself. He left these enterprises in various stages of execution, ranging from books ready for the printing to unrealized designs which can testify only to his mature intentions but which, at least, are being carried through to publication in his spirit by those who have been close to him.
