Most literature-review advice tells you how to structure the written review: thematically, chronologically, or by methodology. That is useful once you are writing. It does not solve the earlier, messier problem: you have eighty open tabs, links scattered across email and Slack, preprints in your downloads, and no system for the ones that are not formal citations. This guide is about that stage, collecting and organizing the research links before you write.
To be clear about tools: a reference manager (Zotero, Mendeley) is the right home for formal citations and PDFs you will cite. This guide covers everything around them, the links you are still evaluating, the supporting blog posts, datasets, threads, and videos that inform your thinking but may never make the bibliography. We make Shelfy, a free link organizer, and it fits this in-between job well.
The Real Problem: Two Different Jobs
Organizing a literature review is two jobs that people blur together:
- Managing citations you will cite. Author, year, DOI, the PDF. This is what Zotero and Mendeley do, and you should use one.
- Managing the links you are still working through. Preprints you have not decided on, a methods blog post, a dataset, a useful X thread, a conference talk on YouTube. These are not citations yet, and stuffing them into a reference manager is awkward.
Job two is where tabs pile up and context gets lost. The fix is a single place to drop links, group them, and add a one-line note on why each matters.
A Practical System
1. One inbox for everything. As you find a link, save it to one place immediately, not "I'll remember it." A browser extension that captures the current tab in one click removes the friction that causes the tab pile-up.
2. Group by theme, not by source. Your written review will likely be thematic, so organize links the same way from the start: a group per subtopic. When you sit down to write the "gaps in prior work" section, every relevant link is already together.
3. Add a one-line note per link. Future you will not remember why a link mattered. "Uses the same dataset as Chen 2024, different method" is worth more than the link alone. Notes are the difference between a link dump and a working bibliography-in-progress.
4. Use status labels. Mark each link: to read, read and relevant, read and not relevant, cite. This turns a scary pile into a queue you can work through.
5. Review regularly. A weekly pass to re-group and prune keeps the collection from becoming its own graveyard.
Where Shelfy Fits
For job two specifically, Shelfy gives you:
- Collections per theme, so each subtopic of your review has its own group of links.
- A browser extension to save the current tab in one click, so links land in your inbox instead of a tab you will lose.
- Auto-fetched titles and previews, so a saved link shows what it is, not just a raw URL.
- Free forever, which matters on a student or postdoc budget.
It does not replace Zotero for citations. Think of it as the staging area: collect and group links in Shelfy, then move the ones you will actually cite into your reference manager.
What About Structuring the Written Review?
Once your links are collected and grouped, the writing stage is a separate question: most guides recommend organizing the review itself thematically, chronologically, or by methodology. The advantage of grouping your links by theme from the start (above) is that a thematic structure is then mostly already done. If you grouped by subtopic while collecting, each group maps to a section, and the link organizing and the writing structure line up instead of fighting each other.
FAQ
What is the best way to organize research links for a literature review?
Save every link to one place immediately, group them by theme (matching how your review will be structured), add a one-line note on why each matters, and use status labels like to-read, relevant, and cite. Keep formal citations in a reference manager and use a link organizer for the in-progress links you are still evaluating.
Should I use Zotero or a link organizer?
Both, for different jobs. Zotero or Mendeley is the right home for formal citations, DOIs, and the PDFs you will cite. A link organizer like Shelfy handles the surrounding links you are still working through: preprints, methods blog posts, datasets, threads, and talks that inform your thinking but may not become citations.
How do I stop losing research links in browser tabs?
Save links the moment you find them instead of leaving tabs open. A browser extension that captures the current tab in one click removes the friction that causes tab pile-up. Then group the saved links by theme and add a short note, so the collection stays usable instead of becoming another pile.
How should I group links for a thematic literature review?
Create one group per subtopic or theme, matching the structure your written review will use. That way, when you write each section, every relevant link is already gathered. Grouping by theme from the start is faster than grouping by source and re-sorting later.
