Safaribooks Like Plugin

Hi,

I am building a tutoring site for my client and one of his recent request was to get a way to have a paid subscription service for students to read important notes from the teachers.

Inscope
– Teachers will have word or pdf notes
– These notes should be published online and available to students on subscription
– Students can read it online, but not copy anything from the notes.

Can anyone tell me a good plugin on any solutions others are doing to tackle this use case.

Thanks,
G
