Abstract
A binder comprises front and rear rectangular cover panels, a sheet retaining assembly, and a spine sheet. The rear cover panel has a width between its first and second opposite side margins. The retaining assembly is mounted on the rear cover panel adjacent to the first side margin of the rear panel and extends along the first side margin. The front cover panel has a width between its first and second opposite side margins. The first side margin of the front panel is disposed parallel to the first side margin of the rear panel. The front panel is less in width than the rear panel, and the difference in width between the front and rear panels is greater than the transverse dimension of the sheet retaining assembly. The spine sheet extends between and foldably joined along fold lines to the first side margins of the front and rear panels, and has a width between the first side margins of the front and rear panels. The width of the spine sheet is greater than the difference in width between the front and rear panels.
