8. Call Numbers The second line is always a whole number. If there is a decimal in the number, you will see it. A decimal will drastically change the number so it will be shelved in a completely different location. The second line is always a whole number. If there is a decimal in the number, you will see it. A decimal will drastically change the number so it will be shelved in a completely different location. Example: B BA C CC 3.41 34.1 341 341.5 3.41 34.1 341 341.5 D32 D32 D32 D32 D32 D32 D32 D32

11. Call Numbers Put the following call numbers in order: Put the following call numbers in order: B B B B B B B B B B 340 340 340 340 340 340 340 340 340 340 D32 D211 D7 D681 D51 D32 D211 D7 D681 D51

12. Answer n B B B B B n 340 340 340 340 340 n D211 D32 D51 D681 D7

13. Call Numbers Using the fourth line, put the following examples in order: Using the fourth line, put the following examples in order: B B B B B B B B B B 340 340 340 340 340 340 340 340 340 340 D32 D32 D32 D32 D32 D32 D32 D32 D32 D32 Z541 Z7 Z2314 D67 Z41 Z541 Z7 Z2314 D67 Z41

14. Answer n 340 340 340 340 340 n D32 D32 D32 D32 D32 n B B B B B n D67 Z2314 Z41 Z54 Z7

15. Nothing Before Something Just as there are decimals we cannot see, there are sometimes numbers we cannot see. This is true in a number of titles housed in the Law Collection. Just as there are decimals we cannot see, there are sometimes numbers we cannot see. This is true in a number of titles housed in the Law Collection. Example: K Example: K L41 L41 We know the second line is always a whole number, so imagine the space contains a zero (0). The space is not usually exaggerated as it is here, so it is necessary to be alert to the omission of a whole number.
