Zotero can do this. It cannot always find the metadata but there are additional plugins available too. Additionally the browser plug-in allows you to easily find the item on a library’s site or Amazon and add the metadata and associate it with the pdf/other file.

It’s open source to boot.

I’ve been using Zotero since I was in grad school and at one point wrote large chunks of the BibTeX export. My first papers were added to my library in October 2006. It’s amazing to have a single source of basically every paper I’ve read in the past 16 years and many books, newspaper articles, etc - including notes. I’ve always had it backed to my own WebDav server that has, somehow, survived despite numerous migrations.

The UI is starting to feel a bit clunky, but it’s fine as a standalone application and the mobile version is great too.

Yes, it can be a tad clunky and the mobile app for a long time was just a catalog.

However, their new iOS app [1] is awesome. The ability to read and highlight right in the app is what I have been wanting for years.

I had previously been using the ZotFile [2] plugin to achieve something similar previously. ZotFile is also very powerful, I only used a subset of features.

Zotero is quite possibly the LEAST WORST solution I've found.

I've tried Zotero and Mendeley during my school days. Didn't stick to any of it. But they were good.
