Zotero is an open-source reference manager that helps researchers organize publications, annotate documents, and create citations and bibliographies for academic papers, dissertations, reports, and other research-based writing.
Zotero is an open-source reference manager for collecting research sources, reading papers, and producing citations. Students, academics, librarians, and other writers can keep bibliographic records alongside attached documents and their own notes. A browser connector captures source information from supported websites, while identifier lookup helps add known publications without manually entering every field. The library becomes a working collection for a dissertation, journal article, course assignment, or collaborative research project. Instead of rebuilding a reference list for each document, users select existing records and insert citations through supported writing applications. Imported information remains editable, so researchers can correct incomplete or inaccurate records before using them.
Zotero stores its desktop library locally, allowing work with saved references and downloaded attachments without a continuous internet connection. Optional syncing transfers library data between devices, while attachment syncing uses a separate storage allowance. Researchers who keep project ideas in Evernote can use a dedicated reference manager to handle publication metadata and manuscript citations. The Windows application requires Windows 10 or later; separate desktop editions support macOS and Linux. Browser capture depends on the connector and the information available from each website. Imported author names, publication dates, and item types still need checking, because citation formatting cannot compensate for incorrect source data.
Zotero reduces the repeated administrative work of turning a reading collection into a properly referenced manuscript. Keeping source records available for reuse means a paper collected for one project can support later assignments or publications without being entered again. Linked annotation notes help writers return to the passage behind a quotation, making evidence easier to check during revision. A citation style change can be applied through the writing integration, reducing manual adjustments when submitting to a different journal. Shared libraries give collaborators a common pool of references, while separate personal collections support individual reading and organization. Local access also lets researchers continue reviewing downloaded material during travel or unreliable connectivity. These benefits depend on maintaining accurate metadata and keeping suitable backups, but they give users practical control over both their working sources and the references that eventually appear in a document.
Key capabilities and highlights.
The Zotero Connector saves bibliographic information from supported journal sites, library catalogues, and other webpages. It can also attach accessible PDFs or webpage snapshots when available. Capturing a source while browsing reduces manual entry and keeps the reference connected to supporting material, although imported metadata should still be checked.
Organize references into collections and subcollections, then apply tags for subjects, methods, or reading status. A single item can belong to several collections without creating duplicate records. This supports overlapping projects and lets researchers classify the same paper by both its research topic and its role in a particular manuscript.
Zotero 10 supports nested search conditions and results focused on items, attachments, annotations, or notes. Researchers can combine publication details with annotation properties to locate specific evidence. Searching across selected collections or libraries helps narrow a large reading archive without moving records into a temporary collection first.
Highlight and underline passages in the built-in reader, then add selected annotations to notes. The resulting note entries retain citations and links back to the source page. This keeps extracted evidence traceable while researchers combine observations from several papers into a working outline or literature review draft.
Reading Mode presents PDF text in a reflowable layout with adjustable font, text size, and line spacing. Figures and tables retain their original rendered appearance. Highlights, underlines, notes, and reading position carry between this mode and the standard view, allowing researchers to adjust presentation while continuing their annotation workflow.
Zotero integrates with Microsoft Word, LibreOffice, and Google Docs to insert citations and maintain a bibliography as references are added. Corrections made to library records can be reflected by refreshing the document. This reduces repeated editing when source details change during drafting or when a manuscript needs another citation style.
Edit supported fields across multiple selected records to correct recurring metadata problems more efficiently. Combined with search, batch editing targets a defined set of references. Version 10 also provides undo for many operations, but batch editing does not currently cover item types, creators, or tags, so those require other workflows.
Group libraries let research teams maintain references separately from each member's personal library. Owners can configure membership, visibility, and editing permissions for the collaboration. Eligible groups can also share attached files through the service, giving colleagues access to supporting documents alongside the bibliographic records used in their project.

Common questions about Zotero.
Yes. The application is free and open source. Library data syncing is free, and accounts include 300 MB of online attachment storage. Larger attachment storage plans are optional purchases; the online allowance does not limit how much material you can store locally.
Released on August 24, 2026, version 10.0.1 fixes problems including startup getting stuck while loading items, crashes involving some plugins, note-editing errors, and embedded PDF annotations sometimes failing to appear. It also addresses database access on network filesystems on macOS and Linux.
Yes. The official Windows requirement is Windows 10 or later, which includes Windows 11. The download provided here is the x64 installer. The official requirements page does not specify fixed minimum CPU cores, RAM, disk capacity, or graphics hardware.
Install the connector if you want to save sources directly from supported websites or use the Google Docs integration. It is separate from the Windows desktop installer. You can still add references manually or by supported identifiers within the desktop application.
Annotations created in the built-in reader are stored in the application database rather than automatically embedded in the original PDF. Export a PDF with embedded annotations when you need those highlights and comments to appear in another reader or in a file sent to someone else.
