| FIVEAM | |
| FLEXI-STREAMS | FLEXI-STREAMS implements "virtual" bivalent streams that can be layered atop real binary or bivalent streams and that can be used to read and write character data in various single- or multi-octet encodings which can be changed on the fly. It also supplies in-memory binary streams which are similar to string streams. |
| GETOPT | getopt is a library for processing command-line arguments. The syntax of the command-line is modeled after GNU's getopt_long function. |

| HTML-ENCODE | html-encode is a small Library for encoding text in various web-savvy formats. |
| HTML-TEMPLATE | HTML-TEMPLATE is a portable library for Common Lisp which can be used to fill templates with arbitrary (string) values at runtime. (Actually, it doesn't matter whether the result is HTML. It's just very likely that this will be what the library is mostly used for.) |
| HUNCHENTOOT | Hunchentoot is a web server written in Common Lisp and at the same time a toolkit for building dynamic websites. As a stand-alone web server, Hunchentoot is capable of HTTP/1.1 chunking (both directions), persistent connections (keep-alive), and SSL, but it can also sit behind the popular Apache using Marc Battyani's mod_lisp. |
| HYPEROBJECT | Hyperobject is a Common Lisp library for representing objects. Hyperobject prints objects in ASCII text, HTML, and XML formats with optional printing of field labels and hyperlinks to related objects. |
| IRC-LOGGER | irc-logger is a IRC networking library written by Kevin Rosenberg which uses the cl-irc library to provide multichannel Internet Relay Chat (IRC) logging. |

This way, HTML pages, CSS files and JavaScript code can be generated with the full power of Lisp and its macros. |
| PURI | Puri provides a Common Lisp library for manipulating Universal Resource Identifiers (URI). It is a portable version based on Franz's open-source net.uri library. |

| USOCKET | A universal socket library for Common Lisp. |
| XML-EMITTER | xml-emitter simply emits XML, with some complexity for handling indentation. It can be used to produce all sorts of useful XML output; it has an RSS 2.0 emitter built in, so you can make RSS feeds trivially. |
| XML-PSYCHIATRIST | xml-psychiatrist is a powerful but unstable XML sanity checking Library written entirely in Common Lisp. It uses XMLS. |
| XMLS | XMLS is a small, simple, non-validating XML parsing library for Common Lisp. It's designed to be a self-contained, easily embedded parser that recognizes a useful subset of the XML spec. It provides a simple mapping from xml to lisp s-expressions and back. |
| XMLS-TOOLS | xmls-tools is a Library to supplement use of XMLS. It includes support for parsing with side effects, searching and validating XML. It includes an example side effect parser in the form of a XHTML to text converter. |
