Rene has recently introduced me to a couple of tools that are useful for organization of such lists and references. I’m not sure if it is what you are looking for, but you may be able to make it work. They are:
Dynalist is a basic, simple, yet powerful outlining app that allows you to make structured and indented lists of items. These items can be text, links, images, with an infinite capability of nesting.
Airtable is an online spreadsheet that has additional features and capabilities.
Other than these, Rene may have some additional tools that I don’t know about. I hope these are what you are looking for.
I hope this has been helpful!
