Thanks @dayanbao, @Snowbird and @Khemarato.bhikkhu . As Snowbird said, the links kindly provided by dayanbao are to files in .json format and therefore require conversion into HTML. Apparently the conversion is accomplished using Bilara i\o but the instructions for using it assume a lot of skills (which I don’t have :-/ ). e.g.
I’m comfortable in Windoze but Bhante Sujato assumes a high level of competency in Linux. 
I have the tools to scrape the site if necessary but can’t see what that would accomplish as I’ve already got bilara-data downloaded to my PC. Converting .json to HTML remains the hurdle.
Snowbird, it seems you’ve successfully converted .json to HTML and then to .mobi. Are you using Windoze or Linux? Any tips would be greatly appreciated.
