This guide is meant to help you find Primary Source Materials on World Religions. It is not exhaustive but will get you started on finding primary source materials. It is broken down into General Religious sources, which tends to include a variety of world religions, Western (Eurocentric) Religions and Eastern Religions.
A good way to find additional sources is by looking in you secondary source materials. A lot of times primary sources will be reprinted in these sources or at the very least cited.
Also keep in mind how much language changes over time. You may need to use words in your searches that you wouldn't consider using normally.
Finally, if you find any really good websites, books, or other sources of World Religion primary sources please send them my way and I'll add them to this guide for others in your class.
Good luck!
Below is a list of useful websites for all World Religions. Many of the links are to research guides similar to this one at other universities or colleges so you may not have access to their databases but you can request materials like books and journal articles via Interlibary Loan.
