About CYC-Net
Open Access
The content on CYC-Net is provided open access.
Open access refers to the free, immediate, online availability of information combined with the rights to use these fully in the digital environment. OA content is open to all, with no access fees.
How you can help to keep CYC-Net open access
The core foundation pillar on which CYC-Net was founded is that it will be free to the end user. Forever.
The CYC-Net web site is a repository of tens of thousands of reference articles, videos, presentations and discussion archives.
In 2025, CYC-Net received nearly 3 000 unique daily visitors, and our monthly journal CYC-Online was downloaded an average of 1 512 times each month. Our discussion groups host over 3 000 members.
But to keep CYC-Net running as open access, independent, and available to all, we depend on the support of organisations, educational institutions, associations and individuals who value what we do.
