Artist interviews may be found in newspapers, magazines, and may be posted on the free web.
Note: This can be tricky when someone like Andy Warhol has his own magazine called Interview!!
1. Search for a "specific artist name" with the word interview. Search for a phrase such as "interview with andy warhol"
Samples:
Search for "andy warhol" AND interview in ARTbibligraphies Modern. Since there is NOT a Document Type for interviews, not all results are going to necessarily be interviews.
Search for "interview with andy warhol" in Google.
2. Search for a "specific artist name" and limit to the Document Type: Interview. This is available in Advanced Search for SOME databases. See Art & Architecture or ARTbibliographies Modern (ProQuest).
NOTE: Some of the interviews may be about the artist rather than with the artist.
