***If you have one great book or article in hand, what can you do to find more like it?***
1. Follow citations backward and forward
References are older than the source at hand.
"Cited by" or "Citations" or "Citing Sources" are newer than the source at hand.
2. Click the links for "Related" or "Similar" sources (in Google Scholar and other databases)
3. Look at assigned subject headings; use them to search for more sources.
4. Follow the author (in databases and/or on social media); they might be an expert in the field with more to say!
This was in the list of references for your "River Walk" assignment:
Listening as Activism, the Sonic Meditations of Pauline Oliveros
Plug it into Google Scholar >> Click 'Cited by' and 'Related articles' to see other works that cited this work >> you may find some similar articles!
If there's a list of references, or linked sources throughout, look at them, too.
