Responsa for Bava Metzia 161:10
איתיביה רבה לרב נחמן נאנסו בהליכה חייב ובחזרה פטור מפני שהוא כנושא שכר
Huna Mar, the son of Meremar, [sitting] before Rabina, opposed two Mishnahs to each other and reconciled them. We learnt, BUT IF THEY DECLARE, 'TAKE YOUR PROPERTY AND THEN BRING US MONEY,' THEY RANK AS UNPAID BAILEES, and [presumably], the same holds good if he informs him, 'I have finished it.' But the following contradicts it: If the borrower instructs him [Sc. the lender] to send [the animal], and he does so, and it dies [on the road before reaching him], he is responsible for it. The same holds good when he returns it! — And he reconciled them by the dictum of Rafram b. Papa in R. Hisda's name: This was stated only if he returned it within the period of the loan; but if after, he is not liable.
Teshuvot Maharam
A. After the period, for which A borrowed the book, had passed, A's responsibility for the book became that of a hired watchman. Therefore, if, before he fled, A could have hired somebody to save the book, and did not do so, he was liable for its loss. But if this was impossible, he was free from obligation.

Teshuvot Maharam
A. Since there was a mutual exchange of books, A's responsibility was that of a paid watchman. Therefore, the answer given above (no. 743) is applicable to this case also.

Teshuvot Maharam
A. Since A and B lent books to each other, their responsibilities regarding these books were those of hired watchmen who are not responsible for unavoidable accidents. The question revolves, then, about A's lending the book to his son-in-law. Therefore, upon A's taking an oath that B gave him permission to allow his sons to use B's book, A will be free from any obligation to B. B, on the other hand, may retain A's book, upon taking an oath that he did not permit A to give his book to A's sons for study, and B is further entitled to collect from A's son-in-law (the difference between the value of the lost book and the one B retained) since the responsibility of the son-in-law regarding the book was that of a borrower who is responsible even for unavoidable accidents. If, however, A's son-in-law is willing to take an oath that he did not borrow B's book from A, he will be free from obligation to B, and his oath will not subject his father-in-law to any further obligation.
The question was submitted by R. Moses Azriel b. R. Eliezer Darshan, whose opinion, appended to the question, coincided with that of R. Meir.
