Certainly! There are various websites and references available that can help you create a timeline tracking the major themes and paradigm shifts in American history during the mentioned period. Here's a step-by-step process to help you find the information you need:

1. Start by looking for reputable educational websites or online archives that specialize in American history. These sources often provide timelines and details on major historical events.

2. One reliable resource is the Library of Congress (www.loc.gov), which has a wealth of digital collections and archives related to American history. Their American Memory Collection and the Chronicling America newspaper database can be great starting points.

3. Another valuable resource is the National Archives and Records Administration (www.archives.gov), which provides access to a vast collection of historical documents and exhibits.

4. Consider using academic websites dedicated to American history. Universities and historical associations often maintain websites with comprehensive information, including timelines. Look for reputable sources like the American Historical Association (www.historians.org) or history departments of well-known universities.

5. Use online databases that specialize in historical timelines. Websites such as TimeToast (www.timetoast.com) or Preceden (www.preceden.com) offer tools for creating custom timelines. You can search for existing timelines related to American history or create your own, incorporating the specific themes and paradigm shifts you're interested in.

6. Don't forget to consult scholarly books and articles on American history. Academic libraries and online resources like JSTOR or Google Scholar provide access to a vast collection of historical research, including detailed analyses of major themes and paradigm shifts.

Remember to choose credible sources and cross-reference information to ensure accuracy. Creating a timeline that tracks major themes and paradigm shifts will require you to identify key events, developments, and changes over time.
