Maintainer activity

8 people did triage or write work on this repository in the last 12 months.

Counts unlabeled, assigned, unassigned, milestoned, demilestoned, locked, unlocked over the last 12 months. These are issue and pull request events that require triage or write permission. Commits and code review are not counted. labeled and renamed are excluded because GitHub issue forms record the issue author as the actor. Figures from October 11, 2026. This count is not comparable across projects: each project's automation decides which of these events a person emits.

How this project is maintained

About 14% of issues opened in the past year have never received a reply. Only 15% of open issues come from outside the core team — the tracker reads mainly as internal planning. Work labelled "Regression" is answered fastest, typically in under an hour, while "Papercuts" waits about 5 weeks. 84% of tracked open issues have had no activity in three months, so the open count overstates what is actively being worked. 65% of issues opened in the past year have been closed, leaving a working backlog.

Detailed Description

Zotero is a reference management tool that helps researchers collect, organize, annotate, cite, and share academic sources.

The tool addresses the challenge of managing research materials across multiple sources and formats. It works by allowing users to capture bibliographic information from web browsers, PDFs, and other sources, storing these materials in a centralized library where they can be tagged, annotated, and organized into collections. The system then enables users to generate citations and bibliographies in various formats for their writing projects.

Zotero suits researchers, students, and academics who need to manage citations across multiple papers and projects. It works well for anyone writing in formats that support citation integration, from traditional word processors to plain-text academic writing workflows. The tool is particularly valuable for collaborative research where source lists need to be shared among team members.

The project maintains active development with a continuous integration pipeline that runs automated tests on code changes. The team engages with users through dedicated forums for feature requests and bug reports rather than handling these through the repository itself, indicating a structured approach to community feedback and issue management.
