It seems evident, however, that while a scattered trade in manuscripts was carried on both by the scribes in the towns and between the monastery _scriptoria_, the facilities for the production and manifolding of manuscript copies were hardly adequate to meet the demand or requirements of readers and students. As early as 250, Origen, writing in Cappadocia, was complaining that he found difficulty in getting his teachings distributed. A zealous disciple, named Ambrosius, secured for the purpose a group of scribes whose transcripts were afterwards submitted to Origen for revision before being sent out through the churches. It is further related that Origen became so absorbed in the work of correcting these manuscripts that he could not be called from his desk either for exercise or for meals.[318] S. Jerome, a century later, when he was sojourning in Bethlehem, found similar difficulty. He had among his monks some zealous scribes, but he complained that their work was untrustworthy.[319] Abbot Lupus of Ferrières was obliged (in the ninth century) to apply to monks in York in order to secure the transcribing work that he required. In connection with this difficulty in securing books, it became customary, when copies were loaned from libraries, to secure from the borrower a pledge or security of equal or greater value. The correspondence of the time gives frequent instances of the difficulty in getting back books that had been loaned, notwithstanding the risk of the forfeiture of the pledges. In 1020, Notker writes from St. Gall to the Bishop of Sitten that certain books belonging to the Bishop, for which the Bishop was making demand, had been borrowed by the Abbot Aregia, and that, notwithstanding many applications, he had not succeeded in getting even a promise of their return.[320] In Vercelli, a beautiful mass book which had been loaned by the Abbot Erkenbald of Fulda (997-1011) to the Bishop Henry of Wurzburg, was to have been retained for the term of the Bishop’s life. After the death of the Bishop, reclamation was made from Fulda for the return of the volume, but without success. During the years 1461-1463, the Legate Marinus de Fregeno travelled through Sweden and Norway and collected there certain manuscripts which he claimed were those that had been taken away from Rome at the time of its plunder by the Goths. He evidently took the ground that where books were concerned, a term of one thousand years was not sufficient to constitute a “statute of limitations.”
