- subject words = less hits & better
- keywords = more hits & sometimes worse
A keyword means find the word anywhere--title, author, notes, description, publisher, etc.
Discovering subject strings and subject terms can lead to much better search results. Some examples for this course--
Germany > History > 1918-1933
Poland > History > 1918-1945
Europe, Central > History > 20th century.
Bulgaria > History > 1878-1944
Italy > History > 1914-1922
