ing process began to change, after the Constitution was adopted, with the emergence of official reporters in the late eighteenth century and the early nineteenth century. See Berring, supra, at 20-21. And, later in the nineteenth century, the West Company began to publish standardized case reporters, which were both accurate and comprehensive, making “it possible to publish in written form all of the decisions of courts.” Id. at 21. Case reports grew thicker, and the weight of precedent began to increase — weight, that is, in terms of volume.
The more cases were reported, the harder became the task of searching for relevant decisions. At common law, circuit-riding judges often decided cases without referring to any reporters at all, see Fentum v. Pocock, 5 Taunt. 192, 195, 128 Eng. Rep. 660, 662 (C.P.1813) (Mansfield, C.J.) (“It [was] utterly impossible for any Judge, whatever his learning and abilities may be, to decide at once rightly upon every point which [came] before him at Nisi Prius .... ”), and reporters simply left out decisions they considered wrong or those that merely repeated what had come before. Sir Francis Bacon recommended that cases “merely of iteration and repetition” be omitted from the ease reports altogether, and Coke warned judges against reporting all of their decisions for fear of weighing down the law. See Kirt Shuld-berg, Digital Influence: Technology and Unpublished Opinions in the Federal Courts of Appeals, 85 Cal. L.Rev. 541, 545 & n. 8 (1997). Indeed, the English opinion-reporting system has never published, and does not today publish, every opinion of English appellate courts, even though the total number of opinions issued each year in both the English Court of Appeal and House of Lords combined is little more than 1000 — less than a quarter of the number of dispositions issued annually by the Ninth Circuit in recent years, see note 37 infra.

Martineau, Restrictions on Publication and Citation of Judicial Opinions: A Reassessment, 28 U. Mich. J.L. Ref. 119,136 (1995).23

Federal courts today do follow some common law traditions. When ruling on a novel issue of law, they will generally consider how other courts have ruled on the same issue. This consideration will not be limited to courts at the same or higher level, or even to courts within the same system of sovereignty. Federal courts of appeals will cite decisions of district courts, even those in other circuits; the Supreme Court may cite the decisions of the inferior courts, see, e.g., City of Richmond v. J.A. Croson Co., 488 U.S. 469, 491, 109 S.Ct. 706, 102 L.Ed.2d 854 (1989) (citing Associated Gen. Contractors of Cal. v. City & County of San Francisco, 813 F.2d 922, 929 (9th Cir.1987)), or those of the state courts, see, e.g., Lujan v. G & G Fire Sprinklers, Inc., 532 U.S. 189, 121 S.Ct. 1446, 1452, 149 L.Ed.2d 391 (2001)

In 1986, only 39% of the 884 opinions of the English Court of Appeal were reported. Martineau, Appellate Justice, supra, at 107, 150. “Although technically a judgment need not be reported to be cited as precedent [in England] ... the reality is that unless a judgment is reported it is not likely to be used as precedent.” Id. at 104. Nevertheless, "[t]here does not appear to be among the judges and the bar any current dissatisfaction with the system except that some believe too many, not too few, judgments are reported.” Id. at 107.
