The Duquesne University Center for Legal Information, which is also the website for the Allegheny County Law Library, lists useful links and resources on its web page dedicated to the "Law of the Aged."
Justia - Elder Law Articles
The referenced websites offer many resources, but some are a bit dated -- MegaLaw (updated in 2007) and Virtual Chase (updated in 2004). Still, such academic websites offer more trustworthy website links than would a mere Internet search on a term like "elder law", which often places commercial websites in prominent positions among results.
For another academic presentation of current and detailed legal websites, focused primarily on Pennsylvania, but extending beyond, as previously noted in my posting "PA Legal Research Websites" Shines (05/01/08), see Pennsylvania Legal Research Web Sites, by Dittakavi Rao.
