Chapter XX: Section VII: Duration of Protection

Protection dates from first publication.

_Generally._--The period of protection is for the natural life of the author and for seven years after his death, or for forty-two years from the date of publication, whichever period shall be longer.[301]

_Posthumous Works_ are protected for forty-two years from the date of publication.[302]

_Encyclopædias_ are protected for the life of the proprietor and seven years (by 5 & 6 Vict. c. 45, sec. 18, the proprietor of a collective work enjoys the same rights as if he were the actual author thereof), or for forty-two years from the date of publication, whichever period shall be the longer.[303]

_Reviews_, _Magazines_, _and other periodical works of a like nature_[304] have two separate copyrights, viz.:

i. The proprietor's copyright in the publication, as a whole,
for his life and seven years, or forty-two years from first
publication.
ii. The contributor's copyright in his separate contribution as a
separate work, beginning twenty-eight years after publication of
the collective work, or on separate publication, if such should by
agreement take place within the twenty-eight years, and lasting
for his life and seven years, or forty-two years from first
publication in the collective work.

_New Editions._[305]--As to each edition, the copyright runs from the date of publication thereof, in so far as the matter therein is then first published.

_Joint Works._--Although there is no statutory provision, they are probably protected for the life of the surviving author and seven years, or for forty-two years from first publication.[306]
