RECAP Archive

A research guide to the RECAP Archive and RECAP extension: crowdsourcing PACER federal court documents, full-text docket search on CourtListener, and APIs.

Written and maintained by CASRAI Editorial Board

Last updated

The RECAP Archive is a public-access digital repository that liberates millions of United States federal court records from fee-based paywalls. Operated by the Free Law Project, the archive crowdsources court dockets and PDF filings purchased through PACER (Public Access to Court Electronic Records), making them freely accessible to researchers, legal practitioners, journalists, and the public. In empirical legal scholarship, the repository serves as a foundational open-data asset, removing financial barriers that historically restricted computational docket analysis to well-funded institutions.

For scholars mapping what legal studies encompasses across quantitative and empirical domains, RECAP transforms how litigation data is gathered. Rather than incurring statutory PACER per-page retrieval fees for every docket sheet and attachment, researchers can query an open repository integrated directly into CourtListener and mirrored to the Internet Archive.

What it is

The RECAP Archive is the document repository component of the RECAP Suite, an open-source initiative founded in 2009 at Princeton University’s Center for Information Technology Policy and maintained since 2010 by the Free Law Project. The name “RECAP” is PACER spelled backward, reflecting its mission to invert the closed economics of federal court access. In the United States federal judiciary, court filings are public records; however, the Administrative Office of the U.S. Courts charges user fees for searching dockets and downloading documents through PACER, creating significant costs for large-scale data collection.

The archive functions as a crowdsourced collective good. When an individual installs the free RECAP browser extension and purchases a document on PACER, the extension automatically and anonymously uploads a copy of that file to the central archive. When subsequent users search for that same document—whether through PACER with the extension active or directly via CourtListener—the system provides the file without charge. Beyond individual user uploads, the archive ingests all free opinions published by federal courts and receives batch contributions from academic institutions and non-profit research teams.

Who runs it and what it covers

The archive is developed, maintained, and legally hosted by Free Law Project, a 501(c)(3) non-profit organization focused on making legal ecosystems more competitive and equitable. Technical operations are directed by Free Law Project software engineers, supported by open-source contributors who maintain the Juriscraper extraction framework and automated parsing pipelines.

The repository’s coverage spans key tiers of the American federal court system:

  • Federal District Courts: Civil and criminal case dockets, motions, briefs, judicial orders, and evidentiary exhibits filed through the CM/ECF (Case Management/Electronic Case Files) system across all 94 federal judicial districts.
  • Federal Bankruptcy Courts: Claims registers, petitions, and reorganization proceedings across federal bankruptcy jurisdictions.
  • Federal Appellate Courts: Dockets and appellate briefs from the 13 U.S. Courts of Appeals and the U.S. Court of Appeals for the Federal Circuit.
  • Free Federal Opinions: A complete collection of free judicial opinions published through court websites and PACER written opinions reports.
  • CourtListener Integration: All RECAP filings are indexed in CourtListener’s search engine, allowing full-text searches across tens of millions of docket entries and OCR-processed PDF documents.

To protect privacy and uphold court confidentiality rules, the RECAP system enforces rigorous technical safeguards. The software automatically detects and excludes sealed cases, restricted docket entries, and in-camera filings. Filings containing unsealed personal identifiers are subject to automated scanning tools (such as Free Law Project’s X-Ray tool) to detect improper redactions.

How to search or use it

Researchers can interact with the RECAP Archive through browser tools, the CourtListener web interface, or programmatic APIs:

  1. Installing the RECAP Extension: Add the official RECAP extension to Google Chrome, Mozilla Firefox, Apple Safari, or Microsoft Edge from the browser’s extension marketplace or free.law/recap.
  2. Browsing PACER with Active Crowdsourcing: Log into PACER as usual; the extension runs in the background. When viewing a docket, blue RECAP icons identify documents already in the archive for immediate free download. Newly purchased documents are uploaded automatically.
  3. Searching via CourtListener: Navigate to CourtListener’s RECAP search interface to perform full-text queries across court filings, filtering by jurisdiction, judge, filing date range, and document type.
  4. Setting Docket and Keyword Alerts: Configure automated docket alerts for ongoing litigation or RECAP search alerts for emerging keywords, receiving real-time email notifications when new entries are uploaded.
  5. Using the NEF Notification Handler: Attorneys can configure their ECF accounts to forward Notices of Electronic Filing (NEF) to @recap.email, automatically liberating the one free copy provided to case counsel.
  6. Programmatic API Access: Query CourtListener’s REST API to retrieve JSON-formatted docket metadata, case summaries, and document download links for computational research pipelines.
  7. Bulk Data Ingestion: For large-scale corpus linguistics or statistical modeling, download daily bulk data dumps or establish direct PostgreSQL replication feeds to maintain a local database copy.

Strengths and limits

Empirical legal researchers must consider both the capabilities and the operational boundaries of the RECAP Archive:

Strengths:

  • Elimination of Cost Barriers: Bypasses the $0.10 per-page PACER fee structure, allowing researchers to study federal litigation trends without prohibitive grant budgets.
  • Full-Text Searchability: Unlike PACER, which restricts searches primarily to metadata and docket numbers, CourtListener applies optical character recognition (OCR) to documents, enabling full-text keyword searches across briefs and exhibits.
  • Long-Term Archival Preservation: Files are systematically mirrored to the Internet Archive, ensuring durable digital preservation and open scholarly citation.

Limits:

  • Non-Comprehensive Coverage: Because the archive relies on crowdsourced uploads and targeted scrapes, it does not contain 100% of all federal filings. High-profile commercial or constitutional cases are thoroughly covered, while routine cases may have missing attachments.
  • No State Court Dockets: The RECAP Suite operates exclusively on federal CM/ECF and PACER systems; it does not collect records from county or state trial courts.
  • Publication and Data Citation: When citing RECAP dockets in academic publications, scholars must account for distinct citation standards across disciplinary venues and law review authorship norms, verifying docket numbers against official court reporters.

Alternatives

Researchers requiring federal court records can evaluate several public and commercial alternatives alongside RECAP:

Platform / Tool Primary Operator Cost Model Coverage Scope Key Use Case
RECAP Archive Free Law Project Free / Open Access Federal district, bankruptcy, and appellate filings (crowdsourced) Academic empirical research, open docket access, automated alerts
PACER (Official) Administrative Office of U.S. Courts Fee-based ($0.10/page up to $3 cap) Comprehensive official federal court records Official legal record verification and real-time case filing
Bloomberg Law Dockets Bloomberg Industry Group Commercial subscription Federal and extensive state court dockets with automated PACER pulls Corporate litigation analytics and practitioner docket tracking
Westlaw Court Wire Thomson Reuters Commercial subscription Federal and selected state filings with editorial summaries Commercial legal practice and precedent research
CourtListener Core Free Law Project Free / Open Access Federal and state appellate case opinions, oral arguments, judge profiles Precedent analysis and judicial behavior modeling

When sharing extracted datasets or working papers based on public court archives, legal researchers frequently deposit preprints in disciplinary archives (as examined in arXiv vs SSRN comparisons) and maintain strict adherence to data integrity protocols to avoid institutional consequences of research misconduct.

FAQ

Is using the RECAP extension legal?

Yes. Federal court filings in the United States are public government records and are not protected by copyright. The Judicial Conference of the United States and the Administrative Office of U.S. Courts permit the sharing of downloaded documents. The RECAP extension simply automates the public sharing of unsealed documents that users have purchased.

Does the RECAP extension upload sealed or confidential documents?

No. The RECAP extension contains strict automated filters designed to ignore sealed cases, restricted documents, and in-camera filings. Users are advised to log into PACER with general search credentials rather than attorney ECF filing logins when handling sensitive matters.

How does the RECAP Archive differ from PACER?

PACER is the official, paywalled repository operated by the federal judiciary that charges per-page retrieval fees. The RECAP Archive is an independent, non-profit database that hosts copies of documents previously downloaded by PACER users, providing full-text search and free downloads.

Can researchers download RECAP data programmatically?

Yes. Free Law Project provides REST APIs, webhooks, bulk data downloads in CSV and JSON formats, and PostgreSQL database replication for academic institutions and empirical legal researchers.
