I must admit that at first I couldn't find any "Brothers" by doing a search on the links that you provided above.

Only after coming back to them three times did I figure out that I think you meant "Do a find" on each of the documents that your link brings up.

I only recently learned about  this "Find" tool!

If there's anybody else who doesn't know, you click on <Edit> at the very top of the page, A dialogue box opens with <Find on this page> at the bottom of the list. Click on the <Find on this page> and another box opens saying <Find what> Type in any word you want to find and press <Find Next> and the first occurence of the word you want is highlighted!

Thanks Melinda:

It took me a while to figure out that you are pointing out to us that Thomas Brothers edited and published a weekly publication in Philadelphia, called "The Radical Reformer," around 1836!!

You are right. I'd like to know what he said in those publications. From the other links you provided, it seems like it was about "The working man's plight?"
