教廷图书馆紧邻梵蒂冈机密档案馆，里面存放了数世纪来，梵蒂冈的外交往来文书和教皇的文件。

The Apostolic Library is next door to the Vatican's Secret Archives, which contain centuries of Vatican diplomatic correspondence and papal documentation.

只有那块颚骨（公众一直没有见过）、头盖骨碎片以及那张还带有血迹的沙发，则作为苏维埃情报部门的机密档案保存了下来。

Only the jawbone (which remains away from public view), the skull fragment and the bloodstained sofa segments were preserved in the deep archives of Soviet intelligence.
