Treatment criteria:

This enclosure is normally used for large books that are not of great thickness and which are unsuitable for rebinding. Atlases are often candidates, as are oversize but thin brittle books.

We will be constructing a four-flap inner enclosure. The inner enclosure can vary from the example given, but the structure of the outer enclosure shown will accommodate any of a number of variously configured inner enclosures.

An outer enclosure of cloth-covered binders board is demonstrated, though it may be of bare grey/white board with a buckram spine, like the wrapper-type enclosure shown elsewhere in this manual. This variety is limited to hardcover books, as the total is too flimsy if the gray/white board outer enclosure is used for large, thin softcover materials.

One variation on this enclosure is the use of ties. Instructions specific to this accessory are given at the end of the tutorial, and the point at which the ties would be installed is cited in the text.

Tools and materials used in this treatment


board shear
bone folder
corner rounder
glue brush


binder's board
book cloth
20-pt. folder stock
PVA mixture or double-sided tape

Using the Manual

To facilitate convenient navigation and use, the procedural parts of this manual are presented in slide show form. As you can see above, clicking on the image shown on each treatment's front page begins the slide show.

Here are the navigational options within each slide. To view this information in illustrated form see the map image below.

Each slide offers the following capabilities:

* Thumbnail images of the entire treatment procedure are in a vertical column to the left. The progression is downward, beginning at the top and ending at the bottom. By clicking on any of these images, you can go to that point in the procedure.

* Clicking on any page's main image opens a larger version of the image in a separate window.

* Button links are provided to return to this page, to go to the next and previous slides in the series, and to go to the complete table of contents for the entire manual.

* The text is dotted with links to tools, materials, glossary terms, and other treatments. Linked text is gray in color and turns red when the pointer encounters it.
