LexisNexis vs Westlaw vs Bloomberg Law
Estimated reading time: 10–12 minutes
Overview / Introduction
For many law firms, legal departments, and legal operations teams, the everyday practice of law starts with research. “LexisNexis vs Westlaw vs Bloomberg Law” is one of the most searched comparisons in legal technology because these three platforms anchor modern legal research. All provide deep access to U.S. federal and state law, but they differ in content strengths, search experience, pricing models, and best-fit matters. This comparison distills vetted library research and practitioner guides to help you choose with confidence—and shows how to operationalize your choice inside Microsoft 365.
At Automated Intelligent Solutions, we help firms modernize their legal tech stack with Microsoft 365 automation, knowledge management, and process design. Below, we break down the platforms and map them to real-world workflows in Teams, SharePoint, Outlook, and Power Automate.

The Big Picture: What These Tools Have in Common—and Where They Diverge
- All three deliver comprehensive access to U.S. cases, statutes, regulations, secondary sources, and practice tools. Yet each has distinct focus areas and user experiences that affect workflow and ROI (sources: NYU Law Globalex overview; Charleston School of Law Library guide).
- LexisNexis and Westlaw support natural language and Boolean search by default (sources: Globalex; University of Chicago Law Library; Charleston Law guide).
- Bloomberg Law leans more heavily on Boolean “terms and connectors,” emphasizing precision and business/transactional content with integrated dockets (sources: MyCase/Above the Law eBook; Chicago Law guide).
Pricing
- LexisNexis — Contracts typically scale by firm size and content bundles; costs can be high for solos/small firms. Tip: Scrutinize scope to avoid overbuying (sources: MyCase/ATL eBook; Globalex).
- Westlaw — Similar scaled contracting and pricing dynamics to Lexis; monitor bundles and scope (sources: MyCase/ATL eBook; Globalex).
- Bloomberg Law — Winner for predictability: All-inclusive flat fee (for solos, about $475/month) with a minimum two-year contract; fewer “out-of-plan” surprises (source: MyCase/ATL eBook).
Features & Content
- LexisNexis — Federal/state case law and statutes; extensive news; business profiles; international sources. Differentiator: News ecosystem (including LexisNexis Newsdesk). Shepard’s for citator (sources: Charleston Law guide; Harvard Law School Library).
- Westlaw — Broad primary/secondary law coverage; KeyCite for citation checking; recognized litigation analytics and dockets (sources: Harvard Law School Library; Globalex).
- Bloomberg Law — Winner for transactional content: Corporate filings (EDGAR), deal documents, practice centers geared to corporate counsel and M&A, securities, IP, and finance. Built-in PACER dockets (sources: MyCase/ATL eBook; Harvard Law School Library).
Search & Citators
- LexisNexis — Natural language and Boolean out of the box; advanced operators, wildcards, and filters. Shepard’s is synonymous with validation (sources: Globalex; Chicago Law guide).
- Westlaw — Natural language and Boolean with excellent filtering and editorial enhancements; KeyCite widely trusted for citation checking (sources: Globalex; Charleston Law guide).
- Bloomberg Law — Winner for Boolean power users: Emphasizes Boolean “terms and connectors”; some find natural language less robust; BCite is useful but often viewed as less comprehensive than Shepard’s/KeyCite for nuanced validation (sources: MyCase/ATL eBook).
Across all platforms, advanced techniques like wildcards, proximity connectors, and truncation are supported, and consistent query design improves results (source: University of Chicago Law Library).
Integrations (Microsoft 365)
Most productivity gains come from streamlining how research moves across assignments, drafting, review, and knowledge reuse. We help legal teams standardize and automate that flow inside Microsoft 365:
- Research-to-matter capture: Power Automate flows save key cases, statutes, dockets, and news from the browser into a SharePoint Matter Research library with auto-applied metadata (jurisdiction, topic, matter number, citator status).
- Teams collaboration: Pre-templated Teams channels per matter with tabs for Research, Drafting, and Filings; pin SharePoint lists and OneNote; route new artifacts for review.
- OneNote research notebooks: Standardize note-taking (facts, issues, search strings, key authorities, Shepard’s/KeyCite/BCite signals) with a reusable table-of-authorities intake page.
- Outlook to DMS automation: Quick Steps + Power Automate to file docket notifications, alerts, or EDGAR filings into DMS-backed SharePoint libraries with thread IDs and timestamps.
- Knowledge management: Promote high-value assets (50-state surveys, model arguments) into a governed Knowledge Base with versioning and term stores.
- Compliance & security: Microsoft Purview sensitivity labels and DLP to restrict external sharing and protect confidential or MNPI research.
Security & Compliance
- Apply Microsoft Purview sensitivity labels to research files and automate data loss prevention policies for confidential matters.
- Leverage conditional access to protect access to SharePoint/Teams workspaces where research and drafts reside.
- Use governance, retention, and versioning in SharePoint for durable, auditable research repositories.
User Experience & Training
- LexisNexis and Westlaw — Natural language support can speed onboarding for teams accustomed to “Google-like” queries (sources: Globalex; Chicago Law guide).
- Bloomberg Law — Boolean-first environment rewards experienced researchers; may require extra training for natural language users (source: MyCase/ATL eBook).
- All three offer training and research support, and libraries emphasize that search competence matters as much as tool choice (source: Harvard Law School Library; University of Chicago Law Library).
Special Strengths & Limitations
- LexisNexis — News integration and international coverage can be decisive where public narratives or cross-border dimensions matter. Watchout: Pricing strain for smaller practices (sources: Harvard Law School Library; Charleston Law guide; Globalex).
- Westlaw — Strong reputation among litigators due to analytics, comprehensive dockets, and KeyCite. Watchout: Similar pricing concerns for small firms (sources: Harvard Law School Library; Globalex).
- Bloomberg Law — Particularly strong for business/transactional work (EDGAR/SEC, practical tools), includes PACER dockets, cohesive business-law environment. Watchout: Less robust natural language search; BCite often seen as less comprehensive than Shepard’s/KeyCite (sources: Harvard Law School Library; MyCase/ATL eBook; Charleston Law guide).
- Specialty databases: Depending on practice, add premium resources (e.g., CCH IntelliConnect for tax/labor) via integrations or separately (source: Globalex).
Use Cases / Best Fit For
- Litigation-heavy practices: Westlaw for litigation analytics, dockets, and KeyCite (source: Harvard Law School Library).
- Case validation / citation checking: LexisNexis (Shepard’s) and Westlaw (KeyCite) are widely adopted choices.
- Corporate/transactional: Bloomberg Law for integrated SEC filings, deal resources, and company intelligence (source: MyCase/ATL eBook).
- Integrated news + legal research: LexisNexis and Bloomberg Law excel at blending market context (sources: Harvard Law School Library; Charleston Law guide).
Firm size scenarios
- Solos & small firms: If predictable spend matters, Bloomberg Law’s all-inclusive model can simplify budgeting. If you rely on KeyCite or Shepard’s, a carefully scoped Lexis/Westlaw contract may still be worth it—negotiate terms and avoid unused add-ons (source: MyCase/ATL eBook).
- Midsize firms: Mixed practices often benefit from Westlaw (litigation) or Bloomberg Law (corporate). Many succeed with one platform plus targeted specialty databases (source: Globalex).
- Large firms & corporate legal departments: Often favor Westlaw for litigation-heavy portfolios and Bloomberg Law for corporate depth; some maintain dual subscriptions for redundancy and user preference.
What to Do Next: Pilot, Measure, and Operationalize in Microsoft 365
- Pilot two platforms on the same matter: Compare time-to-answer, number of on-point authorities, and confidence in citator results.
- Track outcomes: Measure research time saved, authority quality, and drafting iterations required downstream.
- Standardize workflows in Teams/SharePoint: Capture, tag, and surface research across matters using Power Automate and OneNote.
