As published in 1914 it is PD in US.
Doesn't that apply only to books published in US?

No. It is generally accepted, including by the US Copyright Office, en.WS and Wikimedia Commons, that works legally published anywhere in the world before 1923 are out of copyright in the US. 

(The 9th Circuit of the US Federal Court has ruled that "published" only includes in the US (which, in case of a pre-2002 publication in the US, could still mean that works are copyrighted in the US for 95 years from US publication or until 2047, depending), but nobody else accepts that and I believe Mike Godwin was happy to have a case on the matter to take to the Supreme Court, so the WMF might be happy with such a case.)
