geographic area notation from Table 2 for the Swiss
Alps. |

599 is used for works on mammals and for comprehensive works on
birds and mammals. The rest of the primary number in field 082
consists of 09 Geographic treatment from Table 1 and 94 Australia

the book contains information about birds or not. The Dewey
number 598 in the first 083 field means birds, and the full
number means birds in Australia. The second 083 field has the
Table 2 area number for Australia; it is intended to help users
seeking everything about Australia. |
