I have quite an extensive history of scraping web sites for various data over the years, I’d be happy to help you out but I can’t really know how to help without knowing what website your trying to scrape, different sites have their own challenges (maybe behind a login, or using JavaScript to load content - in which case a http response won’t give you what you’re after, or any number of things really).
If you give me a link to a book you want to download as an example I can take a look and help guide you through it
I WISH signal was ubiquitous. Half of my friends are still using Facebook Messenger so I still have to resort to using SMS for them
