What Is Mendeley and Why Students Use It

Mendeley is a free, open-access reference management tool that helps students collect, organize, cite, and share academic sources. Unlike manual citation methods, Mendeley automates the tedious parts of academic writing:

  • Collecting sources from databases, library catalogs, and the web
  • Organizing references with tags, folders, and notes
  • Inserting citations directly into Microsoft Word and LibreOffice
  • Generating bibliographies in any citation style (APA, MLA, Chicago, and thousands more)
  • Sharing libraries with classmates or research teams

Mendeley is particularly useful for students who work heavily with PDFs, need PDF annotation tools, or collaborate with other researchers. It’s owned by Elsevier, one of the world’s largest academic publishers, which also provides integration with Elsevier platforms like ScienceDirect.

Important: As of May 2026, Mendeley Reference Manager is the current, fully supported version. The older “Mendeley Desktop” is still functional but no longer receives updates.

Important: Close Microsoft Word before installing the plugin.

  1. Open Mendeley Reference Manager (desktop app)

For LibreOffice: Mendeley Cite also supports LibreOffice. Install it through the Tools menu in Mendeley Reference Manager, selecting “LibreOffice” instead of Microsoft Word.


Part 2: Building Your Mendeley Library

Method 1: Drag and Drop PDFs (Quickest)

  1. Open Mendeley Reference Manager
  2. Drag PDF files from your computer directly into the Mendeley window
  3. Mendeley automatically extracts metadata (author, title, journal, year)
  4. Review the extracted information and edit if needed
  5. The PDF is attached and ready for annotation

Best for: PDFs you already have on your computer, such as downloaded journal articles or textbook chapters.

Method 2: Mendeley Web Importer (Best for Online Research)

While browsing any website (Google Scholar, PubMed, library catalogs, etc.):

  1. Click the red Mendeley icon in your browser toolbar
  2. A dialog box will appear listing detected references
  3. Check the boxes for papers you want to save
  4. If available, the PDF will also be saved automatically
  5. Choose a folder (Collection) to organize it, or leave it in “My Library”

Pro Tip: The Web Importer works best when viewing an individual article page rather than a long search results list.

Method 3: Manual Entry (For Books and Non-PDF Sources)

  1. Click “Add new” in Mendeley Reference Manager
  2. Select “Add entry manually”
  3. Choose the source type (book, website, etc.)
  4. Fill in the metadata fields:
    • Author(s)
    • Title
    • Publication year
    • Publisher
    • DOI or URL (if available)
  5. Click “Save”

Note: For books without PDFs, manual entry is often necessary. Always verify the metadata accuracy.

Method 4: Import from Other Reference Managers

You can import your existing libraries from Zotero, EndNote, or other citation managers:

  1. In Mendeley Reference Manager, go to File > Import
  2. Select the file from your other reference manager (usually an .bib, .ris, or .enl file)
  3. Mendeley will import the references and attach PDFs if available
  4. Review and verify the imported metadata

Part 3: Organizing Your References

Creating Collections (Folders)

Collections help you organize references by project, course, or topic:

  1. In the left-hand panel, click “My Library”
  2. Click the + button
  3. Select “Create Collection”
  4. Name your collection (e.g., “Psychology 101 – Fall 2026”)
  5. Drag and drop references into the collection

Best Practice: Create collections by course or major research topic, not by individual paper. This makes it easier to find references later.

Using Tags for Cross-Referencing

Tags let you categorize references across multiple collections:

  1. Select one or more references
  2. Click the Tag icon (or right-click and select “Add Tags”)
  3. Enter tag names (e.g., “methodology,” “theoretical framework,” “key finding”)
  4. Use consistent naming conventions (e.g., always lowercase with hyphens)

Example Tag Structure:

  • #methodology-qualitative
  • #theory-social-learning
  • #finding-customer-behavior

Adding Notes to References

Add quick notes to individual references:

  1. Select a reference
  2. Click the Note icon or press Ctrl+Shift+N (Cmd+Shift+N on Mac)
  3. Type your note in the notes field
  4. Save the note

This is useful for recording your thoughts about a source while reading.


Part 4: Reading and Annotating PDFs in Mendeley

Mendeley’s built-in PDF reader is one of its strongest features, allowing you to annotate directly in the app.

Opening a PDF for Reading

  1. In the left-hand panel, locate your reference
  2. Double-click the reference, or click the PDF icon
  3. The PDF opens in Mendeley’s built-in reader
  4. You can have multiple PDFs open simultaneously

Highlighting Text

  1. Select the Highlighter tool from the toolbar
  2. Choose a highlight color (yellow, green, blue, etc.)
  3. Click and drag over text to highlight
  4. Tip: Use different colors for different purposes:
    • Yellow: Key arguments or findings
    • Green: Methodology details
    • Blue: Definitions or concepts

Adding Sticky Notes

  1. Select the Note tool (sticky note icon)
  2. Click anywhere on the document
  3. Type your comment
  4. Sticky notes appear as floating notes on the page

Adding General Notes

For notes not tied to a specific location:

  1. Click the Info icon (top right of the PDF viewer)
  2. Select the Annotations tab
  3. Type in the “General Notes” field
  4. This note applies to the entire document

Highlight-Based Notes

Add notes directly to highlighted text:

  1. Left-click on an existing highlight
  2. A box will appear for you to add notes
  3. Your note is now linked to that specific highlight

The Notebook Feature (Synthesis Tool)

The Notebook allows you to synthesize information across multiple documents:

  1. Open the Notebook from the left-hand menu
  2. Click “New Page” to create a notebook page
  3. Give your page a title (e.g., “Key Arguments about Consumer Behavior”)
  4. While reading a PDF:
    • Highlight text you want to synthesize
    • Right-click the highlight and select “Add to Notebook”
    • The quote is imported directly into your notebook
  5. Add your own commentary below each quote

Why This Matters: The Notebook helps you build arguments by collecting relevant quotes from multiple sources in one place, making it easier to write your literature review or discussion section.

Managing Your Annotations

  1. Click the Annotations icon (top right of PDF viewer)
  2. See a complete list of all sticky notes and highlights
  3. Click any annotation to jump to its location in the PDF
  4. Right-click to delete unwanted annotations

Syncing Your Annotations

Annotations are automatically synced across devices when you’re logged in. To ensure sync:

  1. Click the Sync button (top right of Mendeley window)

Part 6: Best Practices and Common Mistakes

Best Practices

Organize Early:

  • Create collections and add tags as you import references
  • Don’t wait until the end to organize your library

Use Consistent Naming:

  • Use lowercase tags with hyphens (e.g., #methodology-qualitative)
  • Name collections clearly and consistently

Verify Metadata:

  • Always check that author names, titles, and years are correct
  • Incorrect metadata leads to incorrect citations

Sync Regularly:

  • Click Sync frequently to ensure your library is up to date
  • This prevents data loss if your computer crashes

Use the Notebook:

  • Don’t just annotate—synthesize using the Notebook feature
  • This helps you build arguments across multiple sources

Common Mistakes to Avoid

Mistake 1: Not Checking Metadata

  • Problem: Website metadata is often incomplete or wrong
  • Solution: Always review and edit citations before submitting

Mistake 2: Mixing Citation Styles

  • Problem: Creates inconsistent formatting
  • Solution: Set one default style and stick with it

Mistake 3: Storing Too Many PDFs on Free Tier

  • Problem: You’ll hit storage limits quickly (free tier: 2 GB)
  • Solution: Store only essential PDFs; keep citations only for the rest

Mistake 4: Not Organizing with Collections/Tags

  • Problem: Finding specific references becomes impossible
  • Solution: Create folders by project and tag by topic

Mistake 5: Manually Editing the Bibliography

  • Problem: Breaks the link to Mendeley, preventing updates
  • Solution: Make corrections in Mendeley first, then refresh

Mistake 6: Forgetting to Remove Mendeley Links

  • Problem: Some journals don’t accept hyperlinked references
  • Solution: Remove links before final submission

Troubleshooting

Problem: Mendeley Cite not appearing in Word

  • Solution: Ensure Word is closed during installation, then reopen Word
