Yesterday, I uploaded on my website nearly all of the PDF Dhamma books I had collected on my computer over time. I was reminded by Ven. Pesala about copyright restrictions, and so I have removed documents that clearly stated were not to be freely distributed.
Books include: Visuddhimagga, Vimuttimagga, Abhidhammattha Sangaha, Mindfulness in Plain English, and many more.

If you want to add to that list, send me a PDF and I will upload it.
On retreat until 17 February.
