Most of these extensions can be used simply by downloading them into the library directory and putting the line Include "libname" in your game file.
I have split the list up into several sections of related libraries:
Parser, Scope, Verbs, Meta, Time, Debugging, Misc.
Read the comments at the top of each library for any special instructions; all libraries are compatible with Inform 6.05, library 6/4.
