Retouching, a taboo in paper conservation?
Retouching is among the most sensitive within ethics in conservation since it means to establish the aspect a restored object is expected to have. My opinion is that the looks of an historical object is often as important as its physical-chemical condition, and not intervening provides poor results that might mislead its readability more than a proper intervention. The more we intend to make it as neutral as possible, the least arbitrary, we need to admit that retocuhing requires good taste.

Removing a plastic corset from a manuscript
A personal story, a historic manuscript, a crazy laminating machine and a final outcome. We'll discuss about synthetic polymers, sorts of laminations and encapsulation. All these ingredients are seasoned with PFTE, TFA, HFIP, PE, DMSO, PET... cling, dong and BOOM!... An explosive -but most irresistible- cocktail.

Or how to remove pressure sensitive tapes, without removing them. We have spoken about bibliopaths, about misuses and how to eradicate its effects... But, what happens when the artefact itself causes its own degradation?
“Smart books” and bibliographic terrorism
Terrorists do not always carry explosives or mallets, nor they come from overseas, it may even be people in charge of collections. We ought to deal with them to safeguard "smart books": books intelligently made, such that no material interfere with each other, on the contrary, they create formidable synergies. Each one has its peculiarities, its beauty and its function. They represent a compendium of technology, art, society and culture at the time and place in which they were created.

Gone with the wind
I don’t like much having war books, but I must admit that this one is particularly beautiful. The velvet binding seemed to me a challenging issue on the restoration, which did not have major complications besides this. I show the restoration of this book because of the headaches it has given me when solving the lost areas, the wooden work. The considerable losses on a laborious woodcarving work, and the lack of originals of many of the missing pieces fairly complicated the subject (the shields on the corners were different).
