TLDR: I made a Kindle like white-label digital library that doesn't allow users to download files and also makes replication (piracy) of pdfs harder than usual. Would it be useful for you? ........................ Hello PH 👋 I recently made a digital library for a client. It was a freelance gig. They are a journal that sells research content as PDFs and had two strict requirements: The pdfs should be view-only. Users should not be able to download them (to prevent sharing) It should be hard for motivated individuals with the intent of piracy to replicate the pdfs easily I feel I have sufficiently delivered on the requirements. Hence, I am thinking of launching this digital library as a SaaS. Have you even felt the need of such a digital library? Kindly let me know your thoughts. ........................ At the beginning of the gig, I felt that this digital library addresses some important issues related to selling PDFs, hence I planned on releasing it as a SaaS after project completion. I negotiated the contract accordingly with my client.
