Kekewich was upheld with a clearer definition of the right of restraint.
The Court, in deciding (I quote again from Mr. MacGillivray's summary)
that "the proprietors of manuscript letters were, after the writer's
death, entitled to the copyright in them when published, were careful to
make it clear that they did not intend to overrule the authority of
those cases where a deceased man's representatives have been held
entitled to restrain the publication of his private letters by the
recipients or persons claiming through them. The Court expressly
affirmed the common law right of the writer and his representatives in
unpublished letters. It did not follow that because the copyright, if
there was publication, would be in the person who, being proprietor of
the author's manuscript, first published, that that person would be
entitled to publish. The common law right would be available to enable
the legal personal representatives, under proper circumstances, to
restrain publication." That is how the copyright law as regards letters
stands to-day (1912).

The present edition has been revised throughout and in it will be found
much new material. I have retained from the large edition only such
notes as bear upon the Lambs and the place of the letters in their life,
together with such explanatory references as seemed indispensable. For
the sources of quotations and so forth the reader must consult the old
edition.

For permission to include certain new letters I have to thank the Master
of Magdalene, Mr. Ernest Betham, Major Butterworth, Mr. Bertram Dobell,
Mr. G. Dunlop, and Mr. E. D. North of New York.

correspondence of Charles and Mary Lamb, I may say that while these
