Zotero is great for organizing and annotating papers, keeping notes, and building bibliographies.

You can create libraries and sub libraries according to topic, and also create libraries for projects or reading lists. You can file items into multiple libraries, and you can also create shared libraries, allowing your team to share annotated papers.

Finally it can archive offline copies of web pages, which makes it useful for blog articles and other online resources that might vanish.

There's a learning curve, but it's worth it if you find yourself juggling dozens or hundreds of technical papers! Enjoy!
