Collecting Research Sources

Zotero’s primary function is to collect academic sources with a single click. Here are the different ways to add sources to your library.

Method 1: Using the Zotero Connector (One-Click Saving)

This is the easiest and most common method:

  1. Browse to an article, book page, or website
  2. Click the Zotero Connector icon in your browser toolbar
  3. The connector will detect the page’s metadata
  4. Click Save to add it to your Zotero library

For sources without metadata on the webpage:

  1. In Zotero Desktop, click the magic wand icon (Add Item by Identifier)
  2. Enter the DOI, ISBN, or PMID
  3. Zotero searches for the source automatically
  4. Click OK to add it to your library

Method 3: Manual Entry

For sources without online metadata:

Organizing Your Library

A well-organized Zotero library is essential for efficient research. Here’s how to structure your collections.

Creating Collections

Collections are like folders for your sources:

  1. In the left pane, right-click My Library
  2. Select New Collection
  3. Name it (e.g., “Psychology Research,” “Course: HIST 101,” “Thesis Chapter 2”)
  4. Drag sources into collections to organize them

Best practice: Create collections by project or course, not by source type.

Using Tags

Tags provide flexible cross-referencing:

  1. Select one or more items
  2. Click the Tags tab
  3. Add tags (e.g., “methodology,” “theoretical framework,” “key finding”)
  4. Use color coding for different themes

Example workflow:

  • Tag all methodology sources with “methodology”
  • Tag all theoretical framework sources with “theory”
  • Create a “literature review” collection and filter by these tags

Attaching PDFs

Attach full-text PDFs to your sources:

  1. Drag a PDF file onto a Zotero item in your library
  2. The PDF attaches automatically
  3. Zotero indexes the PDF for search and annotation
  4. Double-click the item to open the PDF in Zotero’s built-in reader

Syncing Across Devices

To access your library from multiple computers:

Multiple sources: You can add multiple sources to one citation by selecting several before pressing Enter. Zotero formats them correctly (e.g., (Smith, Jones, 2024)).

Creating a Bibliography

  1. Place your cursor at the end of your document
  2. Click Zotero → Add/Edit Bibliography
  3. Zotero automatically generates the reference list
