How to makes quotes more accessible?

I love quotes, when upset bothered or incapable of expressing myself I look quotes up, reading or watching a movie I jot quotes down that hit me particulary, when battling something I use quotes as tools.

The problem I have is they are everywhere. I can never find the one I want, I have files on my laptop saved in my email, posted on fb and pinterest and on various quote sites, in a file and notebooks and memo pads and books, on post it notes etc.

What is the best way to bring order to chaos? Any ideas for displays? How about making something durable that I can add more to? Should I file according to author or topic key words? Is this why the dewey decimal system is so counterintuitive?
