Profession: book and paper conservator
What does a paper conservator do? Whom does she work for? What skills and knowledge does she ought to have? Preservation and conservation, a field linked to science, history and arts and crafts. A video explains what differenciates us from forgers and shows -among other- how we produce a hand-made suction table to restore paper artifacts, with loads of creativity, a feature most necessary to become book and paper conservator.

Conference about impregnated tracing paper conservation and premier of the video of my latest super-oversized project
Unlocking St. Anthony’s locked manuscript
"Tony, Tony, come around, something’s lost and can’t be found!" Some manuscripts require more than just manual skills to succeed in their conservation, and so we prayed to Saint Anthony to help us unlocking the bookbinding, whose key had been lost forever. Certainly not many renaissance bookbindings have an iron safety lock in their covers and thus this extra holly help was deemed quite necessary. The prayer didn't provide any key, but at least a satisfactory conservation solution was achieved!

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?
New conservation methodolgy to retrieve lost flexibility to brittle tracing paper
Approach to a new methodolgy to retrieve the lost flexibility to brittle paper. Tracing paper -so usual among technical drawings- have in common their transparency, but there are significant differences in the process to make them. The properties and behavior will be very different then. Impregnated papers, for an instance, were applied oils or varnishes to provide them translucency. Explanation restoration of several drawings in which the varnish was removed to replace it later.
Silver-gelatine photographs conservation
New Elimination Procedure for Silver Mirroring. Silver mirroring is a type of deterioration that appears in most gelatin developing-out paper (DOP) historical photographs and black-and-white films. Its treatment involves so many problems that it has often been ruled out. In this article we present a new and simple elimination procedure, which is efficient and offers stable results in the long term. The study of the causes of the formation of silver mirroring sheds light on aspects that had been little explained so far: the fact that this type of deterioration always appears on the surface of the image leads us to consider a mechanism of transport of electrical charges.
Touch and “my crumpled ADLAN tracing papers”
How we restorers motivate with crumpled tracing papers, beautiful papers... This restorer is thrilled with "crumpled ADLAN tracing papers" from CoAC archive, which went through my hands some years ago, and invites you to participate in its digitization.
