There are two types of libraries, the ones that deliver domain specific needs, like a web server, an encryption library, a midi library, a GUI library, a diagraming library, a pdf library, a zip library, a logging library, a database connector library, etc. In Clojure, those all exist, generally by simply reusing the ones that Java or Javascript already invested time and effort into building, though sometimes it has its own as well. The other type of library are generally conveniences, they either simplify existing APIs, add programming constructs, or template/establish a pattern for doing something. These are the ones you tend to not need as much in Clojure, because the language is already so expressive and succinct, and it is pretty trivial to implement your own custom conveniences directly focused to your application needs and your personal preferences.
