First, I need to consider the legal aspects. Sharing PDFs of copyrighted books without permission is illegal. So, I should advise against piracy. But the user might not know that. They might just want to read his works legally. So, directing them to authorized sources is important.

I should also consider that they might not be aware of legal download options, so providing a step-by-step guide on how to find e-books through platforms like Google Play Books, Apple Books, or the publisher's own site could be useful. Maybe even suggest libraries that offer digital lending services if applicable.

Another angle: the user might be interested in his political ideologies or speeches. Maybe there's a PDF version of his speeches available through official channels. Providing information on where to find these resources legally would be helpful.
