Abstract: Binding pages of a book. A spine member has spine coupling features. A plurality of spinelet members each have one or more spinelet coupling features designed to repeatedly conjoin with and disconnect from a corresponding one of or set of the spine coupling features, or to spinelet coupling features of other spinelet members, and have a binding surface designed to provide a permanent or semi-permanent attachment for one or more pages of the book. A kit for binding books may include a device for making spinelet members, the device being adjustable to make spinelet members of varying widths corresponding to thicknesses of desired sections of the book.
