In many of the newer law libraries the English Reports Reprint is the only series covering cases before 1866. Even if, as in the older libraries, the original reports are themselves available, they are frequently so out of the way that it is not normally worth the trouble to consult them. Unfortunately, however, a reader who finds some abbreviated reference to a case decided before 1866 cannot be sure that it will be found in the Reprint. Despite the claim in the Index Chart that the Reprint is a ‘complete verbatim re-issue of all the decisions of the English Courts prior to 1866’, it does not include all the collateral reports, nor does it include the specialized reports of Bail Court, Bankruptcy, Railway and Canal, Election, Registration, Local Government, and Patent and Trade Mark cases. Thus the inexpert worker may waste some time before he discovers that, for instance, ‘D. & R.’ is not necessarily to be found in Volume 171, or that ‘Moo. J. B.’ is not a misprint for ‘Moo. L B.’ and is not to be found in Volume 72, or, for the matter of that, any other volume.
