I need a script to scrape a website for books and then combine them into pdfs. The website is a public library and the books number some 22k. So the books can be seen only in "read" mode. They are to be scraped and joined as [login to view URL] script should have resume function and should not redownload completed books. But if any book is incomplete then they should be downloaded.
I have attached a screenshot of the "read" mode.
