The term "docket" is used for an official court book that contains all the information on court cases – a written list or a document of judicial proceedings. It also includes information such as the actions required on case logs, and reference to the cases or judicial dates on the court calendar.
This book is usually kept with the court clerk and should contain entries of all the proceedings in a case. The court clerk is also responsible for writing brief notes related to the court case in the docket. These notes clearly list all the actions taken in court on a particular day and during a particular case.
A docket can also be understood as a roster prepared and maintained by the clerk, which includes current list of cases, pending trials and so forth. Such a list may include cases for a day, week or a month.
Court dockets help with managing caseloads.
