A manuscript (abbreviated MS for singular and MSS for plural) was, traditionally, any document written by hand or typewritten, as opposed to mechanically printed or reproduced in some indirect or automated way. More recently, the term has come to be understood to further include any written, typed, or word-processed copy of an author's work, as distinguished from the rendition as a printed version of the same.
Before the arrival of prints, all documents and books were manuscripts. Manuscripts are not defined by their contents, which may combine writing with mathematical calculations, maps, music notation, explanatory figures, or illustrations.
The word "manuscript" derives from the manūscriptum (from manus, hand and scriptum from scribere, to write). The study of the writing (the "hand") in surviving manuscripts is termed palaeography (or paleography). The traditional abbreviations are MS for manuscript and MSS for manuscripts, while the forms MS., ms or ms. for singular, and MSS., mss or mss. for plural (with or without the full stop, all uppercase or all lowercase) are also accepted. The second s is not simply the plural; by an old convention, a doubling of the last letter of the abbreviation expresses the plural, just as pp. means "pages".
A manuscript may be a codex (i.e. bound as a book) or a scroll. Illuminated manuscripts are enriched with pictures, border decorations, elaborately embossed initial letters or full-page illustrations.
