The February, 2004 issue of Cobblestone magazine is all about tenements. It is in child-friendly language. You can access all of these articles online (outside of the building you will need the GALE password) by clicking on this link. Below are some particularly good articles.
*The articles are much, much better in print because there are excellent photos not present in the database version of the article. Please ask for a copy of the printed magazine from the library.*
New York City's Tenement Museum is a fabulous place to visit, both in real life and online. Here are some great resources on their site.
