This document discusses how publisher access policies can break library workflows by being incompatible with how libraries authenticate users and link to resources. It provides three case studies of libraries that face "broken access" due to publishers not supporting the libraries' preferred authentication methods like Shibboleth single sign-on or not allowing the use of proxies needed for remote access. The document advocates that libraries plan their access strategies considering how readers, library technology, and external discovery services integrate with publisher access policies and authentication options.
