Your proposition is good and I will lend a book to you next time.¡¡(¡Ö°Û¼Á¤Î¥Þ¥Í¥¸¥á¥ó¥È¡×¤È¤¤¤¦ËÜ) Hope the others¡¡will follow you. Regards Steve P.S.) I guess most people would not take notice but "rent" means to hire out something for money or to pay money to hire something. I guess what you meant was "lending/borrowing" (these words per se do not imply money). I would say 'Book exchange'. = ¥ï¥ó¥Ý¥¤¥ó¥È±Ñ¸ì¤Ç¤·¤¿¡Ê^_^)
