Encyclopedias are a good place to start in order to get background info, brainstorm, and find topic ideas. You can narrow your search to e-books only.
Some encyclopedias are available and can be checked out, while others cannot. Many encyclopedias are also online. Use the RIT Libraries Catalog below to find encyclopedias and books on your chosen topic. I also did a coronavirus search and found this recent book.
You can also use the CREDO Reference database to find information about your topic.
