Newspaper archives as a photo source

I saw an ad today in the Arizona Republic, the largest newspaper in the state where I live, advertising a search feature for their archives, which the ad said dated back to 1862. That sounded like a decent source and the right time period (pre-1916) for this type of web site so I checked it out, thinking I could find a new image source and pass it on to all of you. As it turns out, this is not really a new function of their online edition, azcentral.com, but enhanced capability due to an alliance with ProQuest and thus not free or particularly cheap. This is especially true if you live in a part of AZ close to a major library which has the Republic and other newspapers archived on microfilm, already accessible to the public for free. Granted, you cannot do a random-access search of a roll of microfilm but an individual already paying for domain name registration and high-speed internet access cannot really afford to be paying for content to put on her or his site, thus I will pass. If you are interested, check it out at pqasb.pqarchiver.com/azcentral/offers.html for details on pricing ($1.20 - $3.95 per item), then click on "About the Archive" for usage terms (personal use only, not to be republished - which means no using on your website) and time period covered (1890 forward, not 1862 as advertised.) Someone's attorney must have written this page because it includes the warning that "the information in any particular article may be outdated or superseded by additional information.
