Does anyone know how to obtain articles from things like NY Times, The Nation, Washington Post etc. without paying for subscriptions to them?

I am writing a book currently and found many sources in The Truth About Hungary which are really interesting but I'd like to read the originals

Edit: Sorry I should've specified - I meant more for historical articles as I'm reading some books like Herbert Apheker and even Stalin where I'd like to see what Financial Times was saying in 1930s....NY Times in 1950s etc
