A Linkable Federalist Papers On-Line:
Now here's a nice on-line resource brought to the web by Edward O'Connor. A version of the Federalist Papers to which it is easy to link.
Of course, there are various webbed versions of the Federalist Papers on the Internet already. . . . Unfortunately, I haven't been able find one that was simultaneously nice-looking and useful (useful insofar as pinpoint linkability is concerned, at least). There are some that provide fine-grained linking, but frankly they look like Fisher-Price My First Website.

So I went ahead and made federali.st, an online edition of the Federalist Papers which is pleasant to look at and provides paragraph-level permalinking.

Web geeks might be amused to know that each paper is marked up in the hAtom microformat with an elastic layout, so (among other things) you should be able to increase or decrease your browser's font size and things will still look good.
Try it out.
