Startup Idea: E-books Organizing Software Solution

Startup idea to develop a software solution aimed at effortlessly organizing and sorting large collections of e-books based on various metadata such as author, publisher, genre/topic. This solution will cater to businesses, hobbyists and individuals with extensive e-book libraries.

As a hobbyist in several fields with a significant amount of literature (history, programming & game design, firearms), I have a very large collection of e-books on this, generally in PDF format. However, my collection is extremely disorganized. A piece of software that can sort e-books based on metadata (incl. author, publisher, genre/topic, etc.) would go a very long way towards making my life much easier. I am sure that there are businesses and other hobbyists that would appreciate and pay for this product as well.
