This list of first-class cricket records itemises some record team and individual performances in first-class cricket. The list is necessarily selective, since it is in cricket's nature to generate copious records and statistics. Both instance records (such as highest team and individual scores, lowest team scores and record margins of victory) and season and career records (such as most runs or wickets in a season, and most runs or wickets in a career) are included. Officially, there was no "first-class cricket" in Great Britain before 1895 or in the rest of the world before 1947 (see First-class cricket for details of the official rulings). The performances noted in this article include several which occurred in earlier years but it is understood that all were achieved in matches that are retrospectively recognised by most historians or statisticians as first-class (i.e., unofficially so). Some matches have not been universally accepted as first-class for statistical purposes and there are thus variations in published cricket statistics, mainly because of the different proposals that have been made for the starting date of the statistical records, ranging from the 17th century to 1895. Records shown here are quoted by either CricketArchive or Wisden Cricketers' Almanack, unless otherwise stated. Notation Team notation 300–3 indicates that a team scored 300 runs for three wickets and the innings was closed, either due to a successful run chase or if no playing time remained. 300-3d indicates that a team scored 300 runs for three wickets, and declared its innings closed. 300 indicates that a team scored 300 runs and was all out. Batting Notation 100 indicates that a batsman scored 100 runs and was out. 100* indicates that a batsman scored 100 runs and was not out. 100* against a partnership means that the two batsmen added 100 runs to the team's total, and neither of them was out. Bowling Notation 5–100 indicates that a bowler captured 5 wickets while conceding 100 runs. Team records Team scoring records Greatest margins of victory by an innings Qualification: Innings and 550 runs. Greatest margins of victory by runs Qualification: 575 runs. Victory without losing a wicket Ties There have been 33 ties in first-class cricket since 1948. Before then, a tie was sometimes declared where the scores were level when scheduled play ended, but the side batting last still had wickets in hand. Matches where this happens are considered a draw today,
