Seemed to have been published (8)
I believe the answer is:
appeared
I believe this is a triple definition!
'seemed' is the first definition.
('appear' can be a synonym of 'seem')
'to have' is a link.
'been' is the second definition.
(appearing is a kind of being)
'published' is the third definition.
(I've seen this before)
(Other definitions for appeared that I've seen before include "published" , "Became visible" , "Came into sight" , "Seemed - performed - emerged" , "Turned up" .)
