"The monthly parts of all four series (Appeal Cases, Queen's Bench Division, Chancery Division and Family Division) will from now on be published together in a single cover. There are several reasons for this. Producing and printing the sereis parts individually is very expensive and not very environmentally friendly. The monthly parts for individual series can be very small, and we have sometimes had to delay publication of cases because we have not had enough to make a part. Publishing the series together within a single cover will increase flexibility and enable some cases to be published sooner than would otherwise have been the case" -- letter from publisher 2015
