This video tutorial demonstrates how to effectively remove a label that was adhered over an original leather book spine. The shelf label was glued over a nineteenth-century split book spine. Animal glue was used on this label (label is now historical evidence of this book). A conservation decision was made to remove the label in order to restore the book. Moisture is required to remove the paper label, however special care must be given to ensure the leather does not get wet. Careful attention to not over moisturizing can avert the following issues: hydrolysis, distortion, discoloration and hardening of leather.

Carboxymethyl cellulose (CMC) 4% is applied over paper label. In order to moisturize the paper label and react with the animal glu...

For those who always asking; why don't you use gloves in most of your YoutTube video tutorials about books and paper conservation. The answer is: most of the conservators believe that using gloves in many cases make them clumsy and more likely to create more damage to the object. Moreover, wearing gloves actually increases the potential for physically damaging fragile material through mishandling. I understand it looks more professional and in many times showy to watch a conservator wearing blue surgical gloves, but actually, it is not in need in most of the cases, especially in paper and book conservation, it is better to wash hands often rather than to wear gloves.

For rare books restoration and conservation purpose; in many cases, spine lining, and animal glue should be removed (cleaned off) completely, in order to restore and conserve the sewing or the spine.
Several techniques are used for loosening and clean off old glue from spines.
Be careful when you clean off the animal glue from the book spine. Watch this video tutorial, demonstrate one of the most applied practice.

  In this video methylcellulose solution with a concentration of 4% has been used (Viscosity: 2000 cPs at 2% in water, pH 7.0.)

What is Electroluminescent



The most common electroluminescent (EL) devices are composed of either powder (primarily used in lighting applications) or thin films for information displays (Wikipedia).

To put it simply, EL lamps or "high field electroluminescent" lamps use electric current directly through a phosphor to make light. Unlike most lamps, they can be shaped to be extremely flat, or in narrow wire-like shapes. Electroluminescence or "EL" is the non-thermal conversion of electrical energy into light energy. This phenomenon is used in EL lamps, LEDs, and OLEDs (edisontechcenter)

In the field of paper and book restoration and conservation 

EL is a sheet of thin and flexible plasti...
