These books of clay, 8 they had been dried and 9 in an oven (炉), could last 10 as long as stone. Such books will not 11 up in a fire 12 be spoiled (损坏) by wetness; nor will they be 13 by mice or rats. It is true that they could be 14 , but the pieces can be gathered up and 15 together. The Englishman had to work a long time with broken sheets discovered there before he 16 them all put together properly.
There were 30,000 sheets in the library.
Every book was made up of many sheets, as our books have many 17 . It was, of course, impossible to 18 them together as we 19 now with our books. So all the clay sheets had to be 20 and the name of the book placed on every one.
