Addresses are listed, not certified
The initial monitoring list was supplied by the operator. Names such as z library mirror or z library proxy describe common searches; they do not establish who controls a destination. This site does not relay traffic.
Dates belong to observations
Every response has the time of its own check. An old result, an unsupported HEAD request or a redirect should not be presented as a confirmed current replacement address.
How checks work
Checks send an HTTP HEAD request to an allowlisted public HTTPS address and record response metadata, such as the status code and any redirect destination. They do not retrieve page content or follow redirects automatically.
A response describes one technical observation. It does not establish authenticity, affiliation, account access or the availability of any content. Network conditions and server policies may affect the result.
