Disclosed is a binder assembly and an improved method for binding paper documents, particularly short run and full dress documents (SRFDD) that are widely used in numerous contexts, including competitive bidding and investment solicitation. The binder assembly comprises a slide for supporting the bound document, a cover for enclosing the document, and a binder for binding the document. The cover is flexible and printable with a width-adjustable spine portion for titling and identifying the bound document with indicia. The binding method provides for relatively rapid, yet flexible and inexpensive production of bound documents with professional appearance.
