A contact print of a microfiche jacket containing marketing literature for NB Jackets Corp. (Microfiche jacket and microfilm jacket are synonymous.) The jacket is the same size as a standard microfiche but has sleeves for frames or strips of microfilm. Sleeves make it easier to update a fiche. They can be different sizes—in this case 35 and 16 mm—to allow, for example, storing both data and large drawings in the same fiche.

The title of the original 1966 patent, "Microfiche Master," emphasizes that the ability to make copies is a principal advantage of microfiche. Contact prints are a way of distributing multiple copies of the jacket without removing the original from the file. An additional advantage is that, unlike microfilm reels, a microfiche is a unit record analogous to a punch card and will consequently work in a variety of indexing and coding schemes (Stauley 1966). According to the marketing text on this fiche, additional features of the NB Jacket include color coding and notch coding.
