the federal Courts of Appeals in the Federal Reporter and of the federal district courts in the Federal Supplement, and retroactively republished the decisions of all lower federal courts predating the NRS in Federal Cases. All these reporters are also part of the NRS (National Reporter System), meaning that all cases published therein are annotated with headnotes by West attorney-editors, and all those headnotes are then indexed in the West American Digest System (and its electronic version, KeyCite) for easy cross-referencing. Technically, all of West's reporters were originally unofficial reporters published without the express authorization or endorsement of the courts. West reporters have become the nationwide de facto standard used by all federal courts and most state courts, despite their technically unofficial nature. Indeed, over 20 states have discontinued publication of their own official reporters, and a few states with West's cooperation began inserting certificates in the volumes of the relevant West regional reporter to certify it as their official reporter. Both brothers retired to southern California. In 1995, West retained the services of A.G. Edwards and Goldman Sachs in a search for potential purchasers. Thomson purchased West in 1996. Thomson also consolidated into West a number of other law book companies purchased by either Thomson or West, including Bancroft-Whitney, Banks-Baldwin, Barclay, Callaghan & Company, Clark Boardman, Foundation Press, Gilbert's, Harrison, Lawyers Cooperative Publishing, and Warren, Gorham & Lamont. As a condition of the purchase, Thomson sold 52 titles (including the Supreme Court Reporter, Lawyers' Edition) to LexisNexis. Today, West also publishes some treatise titles purchased from Shepard's (but not Shepard's Citations). Through these acquisitions, Thomson has become one of the "big three" legal publishers, along with LexisNexis and Wolters Kluwer. Following the acquisition by Thomson, West was known as WIPG, West Information Publishing Group. From 1997 to 2004, West was known as "West Group". In 2009–10, West began offering buyouts to its U.S. editorial staff as it began to move editorial production overseas. In 2013, West sold its academic publishing, including Foundation Press, to Eureka Growth Capital.
