SuperSearch can also be helpful for finding sources that provide historical evidence about your cultural artifact and its creation, reception, intended message, etc. Use the publication date limiter on the results page to find mentions of the artifact during a particular time period — for example, around the time of its creation or publication. Limit by content type, such as newspaper or magazine articles, or government documents, to look at evidence in the popular press, governmental communications, etc.

See the A-Z Databases page and filter by subject for additional options.
If you find a book through SuperSearch that is only available in print, see if you can find it in the Internet Archive. You can borrow digitized copies of books for up to 14 days with a free account. Access is limited to one user at a time per book, so be sure to return the book as soon as you're done to make it available for others. Change "Metadata" to "Text Contents" to search for keywords in the full content of all of the Internet Archive's digitized books.
