See the list of recommended databases under the Finding Articles tab.
When searching for sources, use your keywords, do not type in whole sentences.
There is no one 'correct' search word to use. Different keywords will give you more results. Think of words that mean the same or something similar as your topic and try those words too. E.g. Coins, Coinage, Mints, Money, Numismatics + specific coins (e.g. denarii, solidi)
You may need to broaden or narrow your search terms depending on your results :
Broader Search: Painting instead of Fresco
Narrower Search: Ceramic (medium) instead of Pottery (object type)
Use the asterisk * to truncate words and widen your search. Byzant* will search for Byzantine and Byzantium
Use quotation marks to keep phrases together: e.g. "Tomb Painting"
Better to use a period name (if there is one) instead of dates or centuries: Anglo-Saxon (5th-11thc), Edo Period (17th-19c Japan) etc.
e.g. search Rebirth AND sculpture AND Buddhism
Dakini AND Symbolism AND Art
Lotus AND Egypt* AND Art
Rebirth AND Tomb Painting AND Egypt*
Try your search terms in different combinations to get the greatest number of results.
