Letter to Confused in Libraryland

Dear Mr. Dewey,

I am thinking of seeking housing somewhere more affordable, like outside the United States, and someone suggested there might be helpful books available in the library. However, I found it a bit difficult to browse the shelves and was hoping you could explain the way books on living and working in other countries are given their special numbers for finding them:

Working and Living: France, 005.446
Living and Working in Britain, 914.1
Living and Working in Italy, 945
Live Better South of the Border in Mexico, 917.2
When in Rome: Living and Working in a Foreign Country, 648.9

Signed,
Confused in Libraryland

Dear Confused:

You seek the kabbalistic and occult. Consult a librarian.
