Genealogists use old books more often than most other people. Indeed, we also want to take excerpts from an old book and publish those excerpts as part of our own family’s genealogy. However, is that legal? Does the book still enjoy copyright protection?
Under U.S. laws, the answer is simple for books published prior to 1924: the book is now in the public domain (not copyrighted). For books, films, and other works published in 1924 or later, however, the question quickly becomes complicated.
Anything published in 1924 will remain under copyright until the year 2020, anything published in 1925 will remain under copyright until the year 2021, and so on.
