Verdict

Use it to find and cite open-access monographs, or to watch new titles in a field through the RSS feed. Licence: CC-BY-4.0 for the site contents: the footer says "If not noted otherwise all contents are available under Attribution 4.0 International (CC BY 4.0)" and links the 4.0 licence. Each book keeps the licence shown on its own record, and some are non-commercial or no-derivatives, so check the book before reuse. Rate limits: Not stated. Signal Lab links only.
