The document advocates for libraries to conduct user experience (UX) research to better understand user needs and behaviors. It notes that traditional surveys are limited and don't capture real user experiences. The author details several UX research projects they conducted at Cambridge University Library that identified unmet user needs and led to new services. The document argues that UX research provides richer insights than surveys, helps create services that users want, and that libraries should "just do it" to learn directly from users.
