It's important to note that the term "Primer Katipunan" actually refers to two different things:
1. The actual Primer: This is a short catechism that Bonifacio wrote to teach the ideals and principles of the Katipunan, the revolutionary organization he founded. It's the original source of the name "Primer Katipunan."
2. A book titled "Primer Katipunan": There is a book with this title that was written by Teodoro Agoncillo. This book is a historical account of the Katipunan, but it's not the same as the original "Primer" written by Bonifacio.
So, to be clear:
* The original "Primer Katipunan" was written by Andres Bonifacio.
* The book "Primer Katipunan" was written by Teodoro Agoncillo.
