The standards for "public domain" keep changing, too, so look before you leap!
Chesil and Hugh's information about John Clare illustrates one way that writing can be held as property when it "should" be in the public domain.
Another -- MUCH nicer -- way is for the author to bequeath all rights to a non-profit organization. I'm not sure what the U.S. and U.K. laws are, exactly, but they generally make a point of extending those rights "indefinitely" or at least much longer than they would last if left to human heirs.
Here are two pleasing examples:
"With no heirs, [DOROTHY PARKER] left her literary estate to Dr. Martin Luther King, Jr. She'd never met the civil rights activist, but always felt strongly for social justice. ... Within a year of her death, Dr. King was assassinated, and the Parker estate rolled over to the National Association for the Advancement of Colored People. To this day, the NAACP benefits from the royalty of all Parker publications and productions."

James Barrie left all the rights to PETER PAN to a children's hospital, and "Section 301 of the UK Copyright, Designs & Patent Act of 1988 (here) granted the Hospital for Sick Children an inalienable right to receive royalties, without limitation as to duration, for "the public performance, commercial publication, broadcasting or inclusion in a cable programming service" of James Barrie's play Peter Pan following expiry of copyright in the work on 31 December 1987."

And here is a not-so-pleasing example:
"The German Welfare Council (GWC), a charity based in London, is said to have received more than £500,000 from publication" of MEIN KAMPF in the U.K. Their spokesperson said, ""When we agreed [in 1976] to the arrangement the generally accepted view was that there was a moral obligation to pass the money to Holocaust victims - but no Jewish charity would take it." ... "In Britain for years the identity of the charity which received royalties ...was not made public." The Red Cross once returned a large donation when they found out it came from MEIN KAMPF. "The book's British publisher, Random House, has announced that it will redistribute the royalties to other 'appropriate' charities"--but it may be hard to find any that will accept the money!

I feel fine about posting the material quoted above,
MOSTLY because I trust the owners of the material to APPRECIATE it, not resent it, and
ALSO because I have made a good faith effort to credit them by citing the web sources.
I feel NOT SO FINE about posting poetry that I think is still under copyright, so I usually refer to a webpage and pass the buck that-a-way.
