_Encyclopædia of Indexes, or Table of Contents_ (Vol. ix., p. 371.).--Your
correspondent THINKS I TO MYSELF inquires respecting the desirableness and
practicability of forming an "Encyclopædia of Indexes, or Tables of
Contents." It was to meet this want (which is very commonly felt) that the
publication of the _Cyclopædia Bibliographica_ was undertaken. The work has
met your approval, and I have the pleasure of announcing that the volume
will be completed on June 1. I think it will meet the desire of your
correspondent and many others, who, "in reading up on any subject, wish to
know whether any author treats upon it, without being obliged to examine
his works, at a great expense of time and labour."
