Beginning Sept. 15, the legal research service VersusLaw will expand its library of federal district court opinions to include cases back to 1950. At the same time, it will raise the monthly prices of its premium and professional plans by $5. The monthly subscription to the premium plan will increase from $19.95 to $24.95 and to the professional plan from $34.95 to $39.95. The standard plan will remain at $11.95 a month.

The standard VersusLaw subscription provides access to opinions from the Supreme Court, U.S. circuit courts, U.S. district courts, state appellate courts, tribal courts and foreign courts, along with a subscription to AdvanceLinks, a weekly e-mail case alert. The premium plan adds selected state statutes, regulations, constitutions and court rules. The professional plan includes everything the other plans do plus the U.S. Code, the Code of Federal Regulations, and access to certain practice-area libraries.

For a review I wrote of VersusLaw, in which I called it “one of the best deals in legal research,” see With Redesign, VersusLaw Remains Useful, Affordable.
