Great to see you yesterday!
As you recall from your research guide, when looking for modern images ARTstor and Britannica Image Quest (both purchased by the library) as well as the Digital Public Library of America and Europeana (both free-on-the-web sources) should be quite useful.
Also in the guide to assist with narratives, as recommended by a fellow clever student, is the JSTOR scholarly journal archive. 🙂
Good luck in your research & do be in touch with any research questions! Ms. Sanborn
