There is a page on this site - Newspapers that has a large number of free resources and links that you can use to search these historic newspapers.
But what about the paid newspaper subscription sites? I have used the three large ones in the U.S. (Newspapers.com, Newspaperarchive, and GenealogyBank). There are other sites where newspapers are available, such as Ancestry.com, British Newspaper Archive, etc. There are pluses and minuses to all of these sites, but this article is not a comparison of these sites.
Why is that you ask? In my opinion, each person should make up their own mind as to what characteristics are important to them and how each of these sites fit your particular preferences.
What are the four most important characteristics? Here are what I believe are those that you should consider:
- Collections Available - just as in Real Estate where the motto is "Location, location, location" - the motto for subscription newspaper research sites is "Database, database, database." I get asked all the time if someone should purchase a subscription to site A. I always ask them first - for the states, cities or areas that you are researching, as well as the dates that your ancestors lived there, does the site have a collection of newspapers available? If it doesn't for a preponderance of your ancestors - and you purchase a subscription - don't complain when you can't find anything. All sites have a list of what newspapers and dates are in their collections. Check those out before you buy.
- User Interface and Searching Features - every site mentioned above (and those not mentioned) have different user interfaces - some are simple and easy to figure out and use; some have richer capabilities and features. I always like to try the "Advanced Search" features because that generally indicates the total breadth of capability. And one MUST read the Help documentation for each of these sites. Generally they will let you know what type of search criteria can be entered - for example Boolean and proximity searches. Quite honestly I have heard many subscribers complain about not finding anything when they haven't even tried to learn all the search capabilities available to them.
- Scan and OCR Quality - the index that the site has created is only as good as the quality of the original scan and the OCR software that they use to build the index. Were the newspapers scanned from originals or from microfilm, or from copies of microfilm? Some of the collections that I have seen have an extremely poor quality image displayed after selecting a search result. This indicates to me that the original image that they applied the OCR process to was degraded and hence the index certainly will suffer. In other words - your ancestor is mentioned but the scan was so lousy that the OCR process could not build an acceptable index entry with the correct )or near correct) spelling of the name.
- Price and Billing Practices - some of the aforementioned sites are 4 times as expensive as the others. Some have a monthly plan, some annually only. Some auto-renew and some do not. If you purchase a subscription it is incumbent on you to read the terms of the subscription as well as the fine print. As always with any purchase online - it is buyer-be AWARE.
Most sites have some sort of free trial or a short time subscription so you don't have to plunk down money for a whole year if your resources are tight and you just want to check out the site.
So check out free old newspaper resources (I suggest Newspaper Links on this site), but don't forget historical newspaper subscription sites - they have different collections available than those on the free sites.
And lastly, don't forget the library. They often have subscriptions to the aforementioned sites but you need to be physically located at the library to search them. And also the library may subscribe to other historical newspaper collections that can be searched, such as Gale, ProQuest, or NewsBank for example.
Your family history research will be enhanced by using all the resources available to you.
