Open Fifth Information

Open Fifth Limited (formerly PTFS Europe Limited) is a UK-based company with the vision to make technology easy for libraries. We focus on enabling library users through high-quality, open source software solutions. Our way of working is characterised by listening, finding solutions, reliable delivery, and above all open communication. Our highly skilled team has a friendly and approachable style in delivering our quality implementation and support services. We proudly work with customers across all library sectors, including public, academic, health, governmental, museum, law and special libraries. The reason so many customers continue to choose us is that we solve problems, we don’t sell software. When libraries join us as a customer, they are gaining the expertise of our developers, trainers, data migration experts, and experienced account managers to support them throughout the journey. As an ISO/IEC 27001:2022 and Cyber Essentials Plus certified company, you can also rely on the quality and integrity of the support we’re providing.
