History Day Research at CSL (Connecticut State Library)

Purpose of Guide

History Day research benefits from using primary sources. The Connecticut State Library (CSL) is a good resource, especially for topics related to Connecticut and/or federal government. Recognizing that travel to our building is not always possible, there is an emphasis on resources with remote access (although not exclusively).

This guide is to supplement our other research guides. Be sure to check the main research guides, as resources listed there are often not repeated on CSL History Day research pages. And be sure to check your local, state, and national History Day web sites.

This guide was originally created as a "scratch pad" for librarians, and not meant for public viewing. We are in the process of changing the focus. Please be patient. Jenny Groome will accept recommendations for the page, but the Connecticut State Library has final decision on how we present our research guides.
