Newsela, the exceptional reading site offering the same article written for different reading levels (see The Best Places To Get The “Same” Text Written For Different “Levels”) has unveiled a new “Library” feature offering similar “levels” of primary source documents.
Access is free to all Newsela resources, though you have to register on the site. A fee is required, though, in order to use advanced features like a virtual classroom.
You can read more about it at TechCrunch.
I’m adding this new resource to The Best Resources For Using Primary Sources.
