This is a list of text-searchable, free to access (no-pay, non-subscription/-membership/-login) online English newspaper sources. As a rule, entries on this list access many thousands or millions of newspaper pages; they are intended to provide a significant resource to aid in building Wikipedia articles, in which citations to reliable sources is the lifeblood of proper content and at the core of all of Wikipedia's content policies and guidelines, such as notability, verifiability, neutral point of view, and no original research. Websites that provide only limited free material, thus cutting off the bulk of a much larger database, such as The New York Times, are not included.
