Lona Manning’s guide to Researching on the Cheap!
Your search might start at Wikipedia or Amazon to develop leads for books and articles.
To get books you need, speak to your friendly local librarian. If your library system doesn’t have it, they might be able to get an inter-library loan. Or go to your library’s website and suggest the book for purchase—they might do it. Librarians are great!
Google Books (and Project Gutenberg) also carry thousands of out-of-copyright books. You might find an older book written about the topic you’re searching on, plus you can find novels written by Austen’s contemporaries, and books that she read and enjoyed.
Even books that are give limited previews on Google Books can be searched if you type in the key words you need.
