Perhaps the user is in a non-English speaking country, and the author is more popular there. I should consider using the appropriate search terms in the local language to verify the author's existence and the legality of the request.
Once I know the publication date, I can check if it's expired. But since the user hasn't provided specific titles or publication dates, I might need to ask for clarification. Alternatively, if the user is looking to create a legitimate PDF download feature, perhaps they have the rights to the content or are part of a legal distribution method.
Alternatively, the user could be looking to create a feature where users can submit the content of a book (like a summary or excerpt) since full text distribution might be risky. But the original request mentions "novel pdf free," which implies the full text.
Also, the user might need guidance on setting up a website for free PDFs. This could involve creating a CMS, integrating PDF.js for viewing, implementing search functionality, etc. They might need technical advice on how to do that while ensuring legal compliance.
