Microfilm is a kind of photographic film on which pictures and writing are made very small, so that a huge pile of paper can shrink into a small roll or reel. Libraries, courts, and companies used it to keep newspapers, letters, and official files without filling a whole room. You read it on a machine that magnifies the image.

Microfilm縮影膠捲is a kind of photographic film是一種相片底片，on which pictures and writing are made very small把圖片和文字都拍得很小，so that a huge pile of paper can shrink into讓一大疊紙可以縮成a small roll or reel一小捲或一小盤。Libraries, courts, and companies圖書館、法院和公司used it to keep newspapers, letters, and official files用它來保存報紙、信件和公文，without filling a whole room不用佔滿一整個房間。You你on a machine that magnifies the image要用一台能放大影像的機器read it來讀它。

Though actually, it is still film in the old camera sense — a strip of plastic with tiny photographs on it — not a movie you watch for fun, and not a computer file.

Though actually不過其實，it is still film in the old camera sense仍然是舊式相機意義下的底片— a strip of plastic with tiny photographs on it一條上面有小小照片的塑膠片—not a movie you watch for fun不是你看好玩的電影, and not a computer file也不是電腦檔案。

Next to microfiche (a flat sheet), microfilm is often the long roll you wind from one spool to another.

Next to microfiche相較於縮影單片(a flat sheet)（一張平的片子），microfilm縮影膠捲is often the long roll you wind from one spool to another通常是你要從一個捲軸捲到另一個捲軸的長條捲片。

It can be a noun (the film itself) or a verb (to microfilm a document = to photograph it onto this film). The word feels archival and a little dated now, because scanning to disc or the cloud has taken its place, but the copies still sit in many libraries.

It它can be a noun可以當名詞(the film itself)（指底片本身），or a verb也可以當動詞(to microfilm a document把文件製成縮影= to photograph it onto this film也就是把它拍到這種底片上)。The word這個字feels archival and a little dated now現在給人一種檔案室、有點過時的感覺，because scanning to disc or the cloud has taken its place因為把資料掃描存到光碟或雲端已經取代了它，but the copies still sit in many libraries不過這些底片副本仍然放在很多圖書館裡。
