旧信撕裂了，先托住还是装透明护套？断成几片要分开判断

A record with minor tears, especially tears along the edges which do not extend into the text, can be handled safely with care and does not require any preventive measures.

限纸页仍能安全拿取的轻微边缘撕裂；不等于文字区或一碰就碎的旧件。

When handling a record with more extensive tears that compromise the integrity of the sheet, place it on a sheet of archival bond paper to provide added support.

纸张支撑是搬动时承托，不是用胶水或胶带固定；不能用任意家用纸冒称档案级。

When one or more tears extending across a significant portion of the paper may advance even with careful handling, use an L-sleeve to support the record and prevent it from tearing in two or more pieces.

仅未断成多片、材料和表面状态适宜且可安全套入的单张；不泛化为所有破损纸张都要塑料套。

仅定义材质和形态，不单独构成所有破纸都应套入的推荐。

Do not use plastic sleeves with records containing loosely adhered media (e.g., charcoal, pastel)

短引仅支持松附着介质这一例；正文用“表面稳定”概括，不扩成自行摩擦检测。

An L-sleeve is usually not a good option for a record torn into two or more pieces. The pieces can move in the sleeve and cause additional abrasions, breaks, and losses along the torn edges.

强调断成多片不宜直接装L套，勿与尚完整但撕裂的纸页混淆。

只是低干预临时保存方式，材料需符合纸本保存用途，不保证家用文具的档案等级。

不教自行补纸、压平、上胶，也不以一般家庭操作代替珍贵原件的专业判断。

Never use tape on any record in an attempt to repair a tear, maintain an association, or for any other purpose.

限纸本原件表面；不是对储存箱外侧封箱胶带的判断。
