There are two sources for the information utilized within the website. All references are found from literature produced by the Watch Tower Bible & Tract Society. The primary resource material that the Society quotes from can predominately be located within the website: www.archive.org. If there is no link to an external website, it is to be understood that the material came from this website.
I have attempted to find all the original source material possible. However, there are some instances where an earlier or later edition is utilized from what the Watchtower Bible and Tract Society utilized. Hopefully, this is not like material the Watchtower has changed such as the January 1, 1989 Watchtower or the within the book, The Truth That Leads To Eternal Life. If you see a book that contains a year plus “edition,” that means I was unable to locate the original book.
If you are an individual that feels that these PDF files could have somehow been tampered with, you’re highly encouraged to head down to your local library to verify this material. If you’re unable to do this or your local library is too small, feel free to go to a website and order the actual book for your own personal use.
Additionally, there are some resources available within various app stores. One example, “A Commentary, Critical and Explanatory, on the Old and New Testaments,” can be found within iTunes here or in the Google Play here.
