Global Technical Reports

The collection centralizes critical literature from national laboratories and technical institutes around the world—field trials, prototypes, methodological studies, and other content that’s hard to access behind registration walls or missing from standard discovery platforms.

The project preserves all full-text items in the nearly defunct NTIS-NTRL, backfills missing items, adds current reports, and extends coverage globally.

Scope

The collection centralizes and preserves at-risk content currently scattered across hundreds of repositories and websites.

By mirroring and expanding the historical vision of the NTIS-NTRL service, Global Technical Reports gives researchers easy, rapid, and stable access to critical literature that’s either not found in standard discovery platforms or hard to access behind registration walls.

Breadth

Core technical disciplines, including:

• experimental simulations
• fluid dynamics
• materials research

Cutting-edge advancements, such as:

• autonomous systems
• renewable energy grids
• digital twins

Historical content alongside new output:

• reports from 134 US government laboratories and agencies that were included in the near-legacy NTRL database
• new reports from the forty-two Federally Funded Research and Development Centers (FFRDCs) and their international equivalents
• global coverage will come from equivalent government research and development laboratories in Europe, East Asia, and Australasia

Application and impact

The collection covers practical applications and supports evidence-based decision-making for complex technical challenges—in sectors such as infrastructure, defense, and space technology.

It facilitates interdisciplinary work across engineering, energy, and industry. Researchers can trace methodological evolution and compare technology pathways across governments with advanced R&D systems.

• defense, security, and dual-use technologies: Drones, robotics, autonomous systems, and cyber-physical systems
• engineering and applied science: Experimental studies, materials research, and propulsion
• energy and climate: Renewable systems, carbon capture, and environmental remediation
• infrastructure: Intelligent transport systems, seismic studies, and urban systems
• public health: Epidemiological modelling and health technology assessments

“By preserving over 900,000 historical items from NTIS-NTRL, and in expanding coverage to the FFRDCs and their equivalents internationally, we’re filling a gap with a unique, international, cross-searchable, technical corpus that did not exist before.” — Toby Green, editor

Backfilling NTIS-NTRL’s declining coverage 2006-2025

In 2006, NTIS indexed 133 US government agencies in NTRL. By 2025, it indexed only one.

Global Technical Reports not only mirrors the NTRL database, it backfills 2006-2025 coverage for all 133 agencies, as far as possible. It also adds summaries to all mirrored items.
