What about having a contribute button? I know this must be a lot of work and it's such a cool idea! If you had a way to contribute on the join page I would chip in for sure :) My husband is a writer and he uses newspapers.com to research a lot of vintage newspapers for historical context. I can imagine this being a great resource for him.

Thanks I might try that! My impression of donation pages is the conversion rate is extremely low but it will be easy to add nonetheless. I might get better results with offering something in return, like Patreon (not sure what kind of patron content I want to regularly produce though) or products.

There is a much larger database of small ads that I am not publishing on the site, mostly because they add a lot of clutter. But to a researcher they may be valuable. Eventually I want to make the backend database available to people like your husband. Something like newspapers.com makes a lot of sense, thanks for the idea!
