The Eyrie Archive, at http://archives.eyrie.org/racc/lnh, is a repository of LNH stories from the past. It's maintained by Eagle, and is the easiest, best-organized, and most consistent way to download older LNH tales. At the moment, it's updated to November 2006.
Files on the Eyrie are archived in gzip files. Many modern browsers are able to read these files, but if yours can't, download the file and use a program such as 7-Zip or WinRar to unzip it.
