then where would you look to locate information on ancient Rome? And Where would look to find the date of the beginning of World War 1?

Answer 1

Also where would you find further information about a specific topic?

I'd use the Table of Contents for information about Rome.

You didn't list it, but I'd start with the Index to find both answers.

Answer 3

Sorry I see that now about World War 1 Where would you look to find furthur information about a specific topic?
