Subject headings are words and phrases which constitute a "controlled vocabulary" to categorize books by subject field. Subject headings often indicate the contents of books in terms that their titles do not use, which often may be very general. Subject headings in online databases are often referred to as descriptors, but they serve the same purpose in locating valuable resources.
Use general subject headings for searching a broad topic or more specific subject headings for a specific aspect of your research topic. You will find (more) headings specific to the subject category within item record. Here are some you may want to try:
New York (N.Y.) -- History
Immigrants -- New York (State) -- New York
Architecture -- New York (State) -- New York
Italian Americans -- New York (State) -- New York -- History -- 19th century
New York (N.Y.) -- Social Conditions
Brooklyn (New York, N.Y.) Race relations
Minorities -- New York (State) -- New York
