It appears that the "c in circle" and/or the word Copyright,
plus the date first published, are the usual choice. There
is no longer any legal necessity for the notice, but it does
serve to indicate that copyright is claimed, and that there is
no intent for the work to be in the public domain.
LC's copyright office seems to take no stand on the punctuation,
but to me the period seems appropriate, because "all rights
reserved" is a sentence in passive voice with an elided
auxiliary verb.
I remember reading somewhere that "all rights reserved" is an old
phrase that no longer carries legal meaning, but it likely does no
harm. At one time it was found in a plethora of languages in
some books, "todos los derechos reservados," "toutes droites
reserve," "alle Rechte vorbehalten," "tutti i diritti riservati,"
and so forth. The words still appear on some web pages, perhaps
having legal meaning in their home countries. For those who
like finding weird web pages, google for "all rights reversed".

It seems to have no subject and no verb, yet it "looks" incorrect
without a capital A and a period. Is it imperative mood? or what? If it
is "not a sentence," should it eschew capitals and periods?
