conservation: rebinding with original covers

  • conservation: rebinding with original covers

    An example from the Historical Society of Pennsylvania's Bank of North America collection. When the book was removed from the stacks, the textblock sewing had broken, and the spine leather was completely disentegrating.

    book date: 1799 - 1800          measurements: 10 x 15 x 1.3"

    I used a wheat paste poultice sparingly to help remove the hide glue on the spine.  After assessing and dry-cleaning the textblock, the folios were guarded with Japanese tissue and wheat paste to allow enough strength for the textblock to be resewn.

    After guarding, the signatures were collated, new front and back signatures of Ingres paper were added, and airplane cotton hinges were tabbed onto the new Ingres signatures. The signatures were resewn onto linen tapes with linen thread.

    The textblock was then placed in the jobbacker for rounding, backing, and the application of spine linings. Airplane cotton hinges were applied, as well as a new hollow was made out of Bugra paper.

    The text block was attached to the original covers with the linen tapes and airplane cotton hinges. Afterwards, the spine was covered with iris bookcloth, and the rebinding was complete.
