About Us
Preserving Aviation Heritage for the Global Community
Online Aviation Library, operated by Sicuro Publishing, is a specialist aviation documentation business built around a legacy preservation mission. Founded by aerospace engineers who lived the industry's triumphs and challenges, Sicuro Publishing reflects more than 25 years of professional experience devoted to acquiring, preserving, organizing, and making historical aviation technical documentation accessible to the worldwide community of restorers, researchers, historians, museums, educators, and enthusiasts.
Our Mission
Our mission is to collect, structure, preserve, and publish surviving original aviation documentation. We believe aviation knowledge should be organized, structured, and accessible. Every manual we preserve, every blueprint we organize, every collection we curate serves the greater goal of keeping aviation history alive and accessible.
We are specialist archival publishers and preservation partners — not a passive repository, but an active documentation preservation operation that acquires, organizes, digitizes, and publishes historical aviation technical records with engineering discipline.
Our Vision and System
We recognize that many individuals and companies make a living providing aviation information — and we respect that ecosystem. We do more because we have a vision: to preserve aviation documentation that risks being lost as the community moves forward.
The aviation community is always looking ahead — new technologies, modern aircraft, current certifications. But in that forward momentum, critical historical documentation gets overlooked, forgotten, or lost. Estate sales scatter collections. Archives close. Knowledge holders pass away. Documents deteriorate in basements and hangars.
We look back to preserve what others overlook.
We are not a museum. We are an active aviation documentation preservation service that:
- Buys from the community — We acquire documentation from collectors, estates, archives, and aviation professionals before it is lost
- Rescues overlooked materials — We preserve documents the community has moved past but future restorers will desperately need
- Reassembles scattered information — We reconnect documents separated by decades and geography into coherent collections
- Elevates the documentation — We add engineering context, historical background, variant mapping, and professional indexing
- Preserves for the future — We ensure today's overlooked paperwork becomes tomorrow's essential restoration reference
- Shares with the community — We make organized collections accessible to everyone who needs them
Our system brings engineering discipline to preservation:
- Structured collections organized by variant, production period, and system coverage
- Engineering norms and standards from the original production era
- Clear scope definition — you know exactly what is included
- Professional indexing and folder hierarchies
- Curated selection based on technical relevance
- Continuous acquisition — We never stop looking for overlooked documentation to preserve
Why Preservation Matters
The aviation community moves forward — and that is good. But someone must look back and preserve what is being left behind.
What happens without preservation:
- Estate sales scatter lifetime collections across dozens of buyers
- Archives close and documents disappear into storage or disposal
- Knowledge holders retire or pass away, taking institutional memory with them
- Original manufacturers' archives are lost in corporate mergers and bankruptcies
- Documents deteriorate in hangars, basements, and forgotten filing cabinets
What we preserve:
- Factory documentation from manufacturers no longer in business
- Military technical orders from obsolete aircraft programs
- Engineering drawings before they are lost to time
- Maintenance procedures before the last mechanic who knew them retires
- Variant-specific documentation the community has moved past
- The links between scattered pieces of information that make collections truly useful
We are the bridge between yesterday's documentation and tomorrow's restoration needs. The 1940s manual gathering dust today becomes the critical reference for a 2030s restoration project. We preserve it, organize it, and keep it accessible.
The Value of a Professionally Built Archive
A single historical document may sometimes exist elsewhere. A professionally assembled, technically organized, and continuously maintained archive containing thousands of related aviation records is a fundamentally different asset.
The value of Online Aviation Library lies in the accumulated archive, technical organization, digitization, indexing, acquisition history, licensing and intellectual-property arrangements where applicable, and the specialist aerospace knowledge required to build and maintain the collection. That represents more than 25 years of sustained professional work — and it cannot be replicated quickly or cheaply.
Inclusive, Not Exclusive
We are committed to being inclusive partners within the aviation preservation ecosystem:
- We work with type clubs, owner associations, and museums — not against them
- We complement official Type Certificate holders and OEM support networks
- We collaborate with restoration communities, sharing knowledge freely
- We support academic research, historical preservation, and educational initiatives
- We provide lifetime updates to all purchasers — ensuring knowledge remains accessible
What Makes Our Collections Different
As aerospace engineers, we bring professional discipline to documentation organization:
Structured Collections with Engineering Rigor:
We do not simply scan and sell PDFs. We acquire documentation from multiple sources, organize it by engineering logic, add historical context, map variants, and create professional folder structures that make sense to engineers, mechanics, and restorers.
Living Archives with Free Lifetime Updates:
Our collections are never finished. As we acquire additional documentation, technical bulletins, variant-specific materials, or supplementary references, we update collections and provide free lifetime updates to all purchasers. Your one-time purchase guarantees access to all future additions and improvements.
Historical Context and Technical Depth:
Every collection includes comprehensive historical background, operational significance, engineering innovations, and the stories of the people who designed, built, and flew these aircraft. We preserve not just the manuals — we preserve the knowledge and heritage.
Engineering Standards and Norms:
We document the engineering practices, certification standards, and manufacturing norms from each aircraft's production era. This context is essential for understanding how these aircraft were designed, built, and maintained.
Our Legal Framework
Copyright and Registered Interests:
Sicuro Publishing holds copyright registrations with the Canadian Intellectual Property Office (CIPO) covering the compilation, organization, indexing, structure, and presentation of its collections. These registrations record Sicuro Publishing's registered copyright interests in the identified works and collections. Under Canadian law, a copyright registration certificate may serve as evidence that copyright subsists and that the registrant is the owner. CIPO does not independently examine the underlying claims of authorship, ownership, or originality when a registration is filed. Sicuro Publishing therefore also maintains the licences, assignments, agreements, and provenance documentation supporting its rights where applicable.
Rights in Underlying Documents:
Sicuro's compilation copyrights cover the original elements of its collections — organization, indexing, structure, and presentation. Rights in underlying historical documents depend upon the legal status and provenance of the individual material, which may include public-domain status, government-work status, licences, permissions, assignments, acquired rights, or other lawful authority applicable to the particular collection.
Licensing Framework:
- For manufacturers no longer in business: Sicuro may hold collective copyright agreements, acquired rights, or other documented interests in documentation archives — the applicable basis varies by collection
- For manufacturers still in operation: Bilateral agreements may permit structured distribution of documentation for obsolete aircraft models no longer in active production
- All content is provided under clear licensing terms with defined scope and usage rights
Who We Serve
Restoration Professionals:
Maintaining airworthy vintage aircraft requires authentic technical documentation. Our collections provide the engineering specifications, maintenance procedures, and structural repair guidance essential for historically accurate restorations. All OAL documentation is supplied for historical reference and restoration-research purposes; persons performing regulated aviation maintenance must independently obtain and use current technical data required by the applicable authority or Type Certificate holder.
Aviation Historians and Researchers:
Primary source documentation is the foundation of serious historical research. Our collections preserve technical materials, production records, and engineering archives organized for efficient research.
Museums and Educational Institutions:
We support museums, universities, and educational programs with comprehensive technical documentation for their collections, exhibits, and academic research. We welcome institutional partnerships and collaborative preservation initiatives.
Owner Associations and Type Clubs:
We work alongside owner organizations, providing complementary documentation resources that support their members' restoration projects, technical discussions, and historical preservation efforts.
Engineers and Technical Professionals:
Our engineering-focused organization makes our collections valuable for technical analysis, comparative studies, and understanding historical design practices.
Modelers and Enthusiasts:
Authentic technical drawings, engineering specifications, and historical photographs enable accurate scale modeling and deep appreciation of aviation heritage.
