Manuscripts today
According to Library and Information Science, a manuscript is any hand-written item in the collections of a library or an archive; for example, a library's collection of the letters or a diary that some historical personage wrote.
In other contexts, however, the use of the term "manuscript" no longer necessarily means something that is hand-written.
In book and magazine publishing, a manuscript is an original copy of a work written by an author. In film and theatre, a manuscript, or script for short, is an author's or dramatist's text, used by a theater company or film crew during the production of the work's performance or filming.
In insurance, a manuscript policy is one that is negotiated between the insurer and the policyholder, as opposed to an off-the-shelf form supplied by the insurer.
The word manuscript is often abbreviated to MS., plural MSS.
