A route to even more US federal and state law. Thanks to an agreement between HeinOnline and Fastcase, 
incidentally a US law database for which the Law Bod has an existing, separate subscription.

“The federal case coverage includes the judicial opinions of the Supreme Court (1754-present), Federal Circuits (1924-present), Board of Tax Appeals (vols. 1-47), Tax Court Memorandum Decisions (vols. 1-59), U.S. Customs Court (vols. 1-70), Board of Immigration Appeals (1996-present), Federal District Courts (1924-present), and Federal Bankruptcy Courts (1 B.R. 1-present). The state case law covers all fifty states, with nearly half of the states dating back to the 1800s. Coverage for the remaining states dates back to approximately 1950.”
Now, when reading an article which cites US case law, look out for citations marked with a light blue highlight. Below is an example from the footnotes of a Harvard Law Review case comment on National Federation of Independent Business v. Sebelius: The Patient Protection and Affordable Care Act
Footnotes to 126 Harv. L. Rev. 72 (2012-2013)
A click on the citation in Footnote 3 takes one seamlessly if slowly – though this may be the fault of my equipment rather than a system fault – to the judgment (with option to download pdf now top left) powered by Fastcase
Fastcase result in HeinOnline
Incidentally, going back to HeinOnline’s homepage – if you click on the Fastcase tab the search box sharpens up to be a case citation tool – so you could use HeinOnline as a tool for finding US cases, not just those cited in articles you are reading
