在曾国藩即将诞生200周年之际，时隔近一个世纪，北京时代华语图书公司策划、凤凰出版社出版了以选用高 档宣纸、高档木质盒子的为装帧历史再现曾国藩的日记真迹——《曾文正公手书日记》，古朴典雅极具收藏价值。作为“中国近代化之父”，面对着近代“发捻心腹 之害”、俄国“肘腋之患”、英国“肢体之患”等诸多问题，曾国藩开近代风气之先，发起了洋务运动。其手书日记在内容上也为我们展示了有关洋务运动的全新画 面。曾氏手书日记中亦是处处为我们展示了曾氏匡时救世的积极行动和主张。如他在同治元年五月初七的日记中写道，“欲求自强之道，总以修政事，求贤才为急务 以学作炸炮，学造轮船等俱为下手工夫，但使彼之长技我皆有之……”。细细观读曾氏手书日记，其中关于洋务思想的史料比比皆是。
