Note 32 — HARVARD LAW REVIEW

"But a doubt has been suggested, whether mere private letters, not intended as literary compositions, are entitled to the protection of an injunction in the same manner as compositions of a literary character. This doubt has probably arisen from the habit of not discriminating between the different rights of property which belong to an unpublished manuscript, and those which belong to a published book. The latter, as I have intimated in another connection, is a right to take the profits of publication. The former is a right to control the act of publication, and to decide whether there shall be any publication at all. It has been called a right of property; an expression perhaps not quite satisfactory, but on the other hand sufficiently descriptive of a right which, however incorporeal, involves many of the essential elements of property, and is at least positive and definite. This expression can leave us in no doubt as to the meaning of the learned judges who have used it, when they have applied it to cases of unpublished manuscripts. They obviously intended to use it in no other sense, than in contradistinction to the mere interests of feeling, and to describe a substantial right of legal interest." Curtis on Copyright, pp. 93, 94.

The resemblance of the right to prevent publication of an unpublished manuscript to the well-recognized rights of personal immunity is found in the treatment of it in connection with the rights of creditors. The right to prevent such publication and the right of action for its infringement, like the cause of action for an assault, battery, defamation, or malicious prosecution, are not assets available to creditors.

"There is no law which can compel an author to publish. No one can determine this essential matter of publication but the author. His manuscripts, however valuable, cannot, without his consent, be seized by his creditors as property." McLean, J., in Bartlett v. Crittenden, 5 McLean, 32, 37 (1849).

It has also been held that even where the sender's rights are not asserted, the receiver of a letter has not such property in it as passes to his executor or administrator as a salable asset. Eyre v. Higbee, 22 How. Pr. (N. Y.) 198 (1861).

"The very meaning of the word 'property' in its legal sense is 'that which is peculiar or proper to any person; that which belongs exclusively to one.' The first meaning of the word from which it is derived—proprius—is 'one's own.'" Drone on Copyright, p. 6.

It is clear that a thing must be capable of identification in order to be the subject of exclusive ownership. But when its identity can be determined so that individual ownership may be asserted, it matters not whether it be corporeal or incorporeal.
