This study was done on a piece of archaeological leather document preserved in Egyptian museum storeroom under No.JE90809 SR 5/13677, excavated 1966. The leather document showed different aspects of deterioration types. Different analytical methods were used for identifying the components of the leather document to explain its mechanism of deterioration process. Analytical methods were used: visual assessment, documentation process by high resolution camera and scanner in multispectral imaging (MSI), diagnostic examinations using Multi Spectral Imaging (VIS-UV-IR), isolation and identification of different types of fungi, investigation of the surface morphology and animal type using digital light microscope (Dino light), stereo microscope (S.M.) and polarizing microscope (P.M.), identification of ink binder, amino acids degradation and tanning materials by Fourier transformation infrared spectrophotometry (FTIR) it is a qualitative analysis to give general information concerning collagen, identification of inks by X-ray diffraction (XRD), measuring the thickness by micro meter. In addition to suggest a new method for Museum show for the archaeological leather document as the preparation of a new method of exhibition is considered one of the most important goal of this study, because the current method of exhibition is considered one of the most important reason for the deterioration of the studied document. The results revealed that the microscopic examinations of samples clarify that the type of skin used was sheep in comparison with the standard samples. Also it explained the deformation of the appearance, contaminations from stains and Analytical Study of the Archaeological Leather Document Preserved in Egyptian Museum and New Proposal for Museum Exhibition Restoration 2 dusts, and damages caused by physical factors. X-ray diffraction results showed that the ink used was made of carbon black ink. In addition the results showed that thickness measurement numbers were different which give indicate to somehow the manufacturing process was not so perfect. Also the results of FTIR proved the degradation of the collagen in the archaeological leather document, the binding agent was Arabic gum and the leather was tanned with vegetable tanning. Isolation and identification of microorganisms clarified the most dominant fungi isolated from the archaeological leather document were: Aspergillus niger, Aspergillus sulphureus, Aspergillus versicolor, Aspergillus sydowii, Penicillium chrysogenum, Penicillium islandicum, Alternaria alternate, Aspergillus flavus, Aspergillus terreus. Finally, the storage of the leather document was very poor which led to different aspects of deterioration. That prompted the author to suggest a new method for exhibition for the archaeological leather document.

Photographic materials have complex structures that present special preservation challenges to the librarian and archivist which most commonly found in libraries and archives. Deterioration which takes place in photographs is an ongoing natural process. Deteriorated photographs may require specialized conservation and preservation treatment which the authors here concentrate on displaying and storing procedures. The Dome Library in South Valley University has a lot of photographic materials which suffer from different deterioration aspects. The authors recommend a combined method of displaying and storing of the photographic albums which can be applied later for all the other materials according to each case study with the developing project of the Dome Library digitizing in Faculty of Arts in South Valley University in Qena. Also some analytical techniques were used in the study: using Visual Assessment, Microscopic Examination, Identification of photo by X-Ray fluorescence, X-Ray diffraction analysis for determining the paper crystallinity, Fourier Transform Infrared Spectroscopy (FTIR) for determining the binder and Isolation and identification of fungi (collection of samples swabs). Finally, the authors design a method to preserve the album supported with Cradle to combine the process of storing and displaying the album in one step.

Two historical mummies dating back to the Roman era, discovered in EL-Salam area in Siywa tombs, their length reached to 170cm, preserved in Hall No.6 of the museum store in Siywa. Both of them wrapped in linen rolls but one of them provided with Cartonnage layer (gesso layer of 2cm) were chosen to the study. The mummies showed different aspects of deterioration types. This study aimsto describe these aspects of deterioration; explain the mechanisms of deterioration resulting from investigations through applying different analyses processes (visual assessment, microbiological investigation, scanning electron microscope (SEM/SEM&EDS), Fourier transform infrared spectroscopy (FTIR), X-Ray florescence (XRF), Stereo Microscope (SM)). Finally,apply appropriate restoration and conservationprocedures to the mummies. Theconservation techniques used were Sterilization procedures; Mechanical and chemical Cleaning processes; Completion of the missing parts of the Cartonnage (Jesso/ gypsum layer); Consolidation, Unfolding and mechanical supporting of the weaken parts of linen rolls; The treatment of the Cartonnage layer cracks and fragments of it; and Storage and Display conditions.The results of investigations revealed that the mummies suffered from a degradation of amino acids as well as oxidation and hydrolysismechanisms.The mechanical andchemical cleaning used removed the surface dust and dirt without damage to thecomponents of the mummies.In general, allthe conservation processes of the mummies revealed its aesthetic value again.
