You can access judicial opinions, orders, and memoranda, as well as documents filed by parties in federal cases. The documents are "available immediately after they have been electronically filed." It is not entirely free, but not terribly expensive: "Access to court documents costs $0.10 per page. The cost to access a single document is capped at $3.00, the equivalent of 30 pages. The cap does not apply to name searches, reports that are not case-specific and transcripts of federal court proceedings. By Judicial Conference policy, if your usage does not exceed $15 in a quarter, fees for that quarter are waived, effectively making the service free for most users."
