Here we have a book that meets the criteria for this treatment. The case-to-text block attachment is intact, boards in satisfactory condition, cover material damaged at spine only. Cover has text and/or graphics which, at least for the sake of example, we will say it is desirable to save rather than obliterate.

To begin, the cover material is cut using a razor knife and metal straight-edge. A vertical cut is made about 1/8" from the board's back edge. The 1/8" wide sliver of cover material still fastened to the boards is lifted and removed, using a microspatula.

Note: While cleaning up a book for a spine repair, caution should always be exercised to avoid damaging the super. If that happens, the job has turned avoidably into a higher-level repair, a (recase with spine repair). Mainly, the precautions involve never cutting into the joint with a sharp knife when removing old cover material, and being particularly careful when removing the remnants of the old turn-in at each of the four corners of the boards.

Horizontal cuts about one inch long are made at the top and bottom of the board, right on the board's outer corner, again following the metal straight-edge with the knife. The old cover material is lifted approximately 1" back from the board edge, using a microspatula. The book is now turned over, and the cutting and lifting in this and the previous illustration are repeated on the other board. The old cover material of the spine is removed (if intact).

A strip of paper 1" to 2" wide is wrapped around the spine of the book, and marks are made on both the front and back, at the following locations:

* at the shoulder of the text block
* about 1" from the back edge of the board

In a conservation lab, the spine repair is a treatment that is done in batches of about a half dozen, so information for each book is written on the paper template made in the previous step. This information includes:

* the length measurement (length of the book's boards, plus 5 centimeters)
* the color of cloth needed to best match or blend with the original cover material
* an abbreviated version of the title; just enough to identify the book

The illustration shows the paper template bearing all the information needed to select the cloth. The template tells us:

Length: This book's boards measure 24.2 cm long, so our cloth needs to be 29.2 cm. long, with the grain running lengthwise or "grain long".

Color: We need rust colored cloth to best match the original cover.

Title: This template is for a book entitled "Which Way Is South Africa Going?" (This is the book featured in the documentation for the spine repair with new cloth going over the old. In our example here, it would actually say something like "Hist. Img./blk./and the length measurement", but the procedure is the same.)

Here we see the paper template with all the information needed to select the cloth for a batch of 7 books, and more information can be recorded on the other side of the paper if necessary. As one might imagine, it's a lot easier to carry the paper template to the materials bins than to carry 7 or more books.

The cloth having been selected from the bins, it is cut to length and marked in accordance with the marks on the template. The outer marks indicate the overall width of the cloth, to which width it has been trimmed.

The inner marks of the template are transferred to a piece of 80 lb. text weight paper. A strip of the paper is cut to this width, the length of the book's boards, and running grain long. This paper is the spine inlay. It is glued with PVA mixture to the backside of the cloth, centered both ways.

Note: If the book requires the use of security strips, it is at this point that the strip is attached to the spine inlay.

The cloth is positioned against the spine of the book with one end of the paper flush with one end of the text block (excluding the headband, if there is one), and with the sides of the paper flush with the shoulders of the text block.

It is a good idea to mark head/tail bearings before starting this step, or at least sometime soon. A simple "H" or "T" written on the spine liner is all that is needed. Sometimes the location of the boards, relative to the text block, can vary from one end to the other, so if the cloth happens to get turned end-for-end it will not fit. Recording head/tail orientation eliminates the problem of the cloth not fitting for this reason.

The cloth is now wrapped around the spine of the book, and with the cloth held tightly to the book, marks are made indicating the corner formed by the top and back edges of the boards. (The cloth has been pulled away from the book in order to make the mark at the back of the board visible. As mentioned, it is held tightly against the book while actually being marked.)

This marking is now repeated at the other end of the book and cloth. The result should look like the illustration.

Now additional lines are marked, using the horizontal (top edge) and vertical (back edge) lines traced from the board corners. A line is marked one board thickness outside the horizontal line, and the vertical lines are simply extended outward.

Cuts of the shape shown are made in the ends of the cloth. These cuts are dissected by the vertical lines and stop at the outer horizontal lines. The cuts are made using scissors, and the blunt point of the cut's inward end makes the turn right at the intersection of the horizontal and vertical lines. Care is taken not to cut inward beyond the outer horizontal line.

The cloth is folded across its width at the ends of the spine inlay, and a piece of cotton twine is laid in the fold. The length of the twine is the width of the spine inlay. The purpose of the twine is to reinforce the cloth, particularly at the book's head end, where it is sometimes hooked by a finger for removal from tight shelving.

The cuts made previously formed the ends of the cloth into three tabs. The center tab only is now folded over double and glued down. The twine needs to stay back in the fold. After gluing the tab down, it is raked with a bone folder to tighten the bond, and the edge of the folder is used to define something of a crease along the twine's inner edge.

PVA mixture is applied to one side of the cloth, stopping at the board edge line. Normally, stopping about ¼" from the paper spine inlay is an accurate enough approximation. The red shaded area in the illustration indicates the area to which the adhesive is applied. No effort is made to glue the undersides of the tabs yet, though some adhesive will get on them, and that is fine.

The cloth is now positioned on one side of the book, working it in under the flap of the original cover material.

Lateral alignment: The edge of the spine inlay should align with the shoulder of the text block.

Lengthwise alignment: The spine of the book is centered (snugly, as a rule) between the cotton twine reinforcements.

The tabs are now glued down, and the inside view of the board should look like the one in the illustration. The procedure is repeated on the book's other side. At this time, the loose flaps of the old cover material are glued down. The inner surface of the flaps are glued, not the spine cloth they will be glued to.

The new spine is now installed, and the inside view should look like this.

Here is the outside view.

The goal in the way of fit is making certain that the corners of the boards are covered and that no bare board is left exposed. The illustration shows a well-executed example.

The book is now placed in a standing press, between edge boards, until the next day.

If the original cover's spine is salvageable, it is trimmed and the backside cleaned of old paper, and it is mounted to the new cloth, as shown in the illustration. If not, a new spine label is made. If a new call number label is needed, one is made. When all labeling has been attended to, the job is complete.

The book is finished and ready for circulation.
