Boston public library officials say two rare and valuable artworks that vanished last month have been found – and they never left the library.

Library officials say the 1634 Rembrandt etching and 1504 Durer engraving were found on Thursday in the library’s print stacks. Officials say the artworks were misfiled.

The disappearance of the art pieces eventually led library president Amy Ryan to announce her resignation on Wednesday, effective on 3 July, saying her leaving would end a “distraction”.

However, Ryan said in a statement on Thursday that library officials were thrilled to have found the missing pieces right in the library.

The Durer engraving is worth an estimated $600,000 and the Rembrandt etching has an estimated value of $20,000 to $30,000.
