Zotero

“It’s free, it’s open source, and it’s the easiest to use for managing sources & citations. A must-have for all you thesis and journal article writers out there.”

“As a certified Old currently in grad school, I love Zotero for organizing my research (this is a screenshot of what I'm currently working on). You can read and annotate within Zotero, produce citations, and there's a Chrome plugin. The free edition does have a storage limit, but you can export a bibliography of collected articles at any time, so cleaning up is no big deal.”

“Great for research but also pdfs of books and articles in my tbr. When I was going to lose my grad school library account, I mass saved books in here.”

“My preferred research organization method. Read, annotate, and produce citations in one place. Free!!!!! with some storage limits, but you can export the entire bibliography of a collection at any time. Using the browser extension is key.”

“Adding citations to your papers sucks. Zotero is a great dumping ground for all of your research sources, and when you're done, it adds a tidy little bibliography right into your paper. Also, it's free.”
