Well, you can download IB Horner’s translation of the entire Pali Vinaya in PDF from the download page, but I assume that’s not what you want?
Are you looking to download only the Bhikkhu vibhanga, as translated by Ven @brahmali ? Perhaps Ven @sujato might be able to help?
Yes, as Faujidoc says, there’s currently no way to download individual books as PDFs. We do plan to revisit this next year.
So it might be available to download it next year?
Indeed, our aim is to build a pipeline so that any of the texts in the new “bilara” format, including the translations by myself and Ven Brahmali, will be available as both epub and pdf, and from the pdf, paper books. At the moment we are focussed on getting the pipeline working for the main website, and we are seeing good progress there. Next we’ll attend to the epub and pdf creation.
