dust off

フランス・パリのルーブル美術館が、所蔵品をオンライン公開するということです。

コレクション総数は48万点以上、しかも無料ということですので小生も早速アクセスしてみようと思いました。

There is nothing like spending a rainy afternoon at a museum, soaking in the beauty and wonder of art and history. Now the Louvre, the world's most visited museum, is letting you do that right from home.

The French museum has released an online platform featuring all of the museum's artworks, consisting of more than 480,000 pieces, the Louvre announced Friday in a press release.

Art lovers and researchers alike will now be able to view the entire Louvre collection online for free.

"Today, the Louvre is dusting off its treasures, even the least-known," Jean-Luc Martinez, the president and director of the Louvre, said in a statement. "For the first time, anyone can access the entire collection of works from a computer or smartphone for free, whether they are on display in the museum, on loan, even long-term, or in storage."

"The Louvre's stunning cultural heritage is all now just a click away!" he added.

"dust off"という表現ですが、しまってあるものを取り出す、という意味で使われる口語表現です。

"dust"はご存知のように埃（ほこり）のことですから、物置かなんかでほこりを被っていた、長年使っていないものを引っ張り出してきてまた使う、といったニュアンスですね。

以前取り上げた、"gather the dust"、"dustup"もどうぞ。
