What Tier 0 means

Every paper archived at Atopos is Tier 0. That means:

  • Free to read, always, for everyone
  • No login required to access the full text
  • No paywalls, ever
  • No embargo period

Tier 0 is not a tier among options. It is the only tier. Open access is an architectural constraint at Atopos, not a policy that can be reversed.

Why processing fees exist

Readers pay nothing. Authors pay a small fee to cover the cost of running the infrastructure. 10% of every fee goes into the Waiver Fund — which pays the fee for anyone who cannot afford it.

The founding cohort (first 100 accounts) receives one free first submission as a recognition of early support.

Preservation

Archived papers receive a permanent Atopos identifier and are deposited to Zenodo for long-term preservation. Papers are not removed from the archive. Retracted papers receive a permanent tombstone record.
