Abstract
Samples from covers and endleaves of sixteenth to eighteenth century books in good conservation state from the Biblioteca Nazionale Marciana in Venice have been investigated by means of electron paramagnetic resonance EPR spectroscopy and optical microscopy to characterize the embedded paramagnetic species and to test differences and similarities of the materials in the two types of book components We detected the MnII FeIII and CuII paramagnetic ions and analyzed their EPR signals by comparing them with previous results in literature of EPR studies on paper Interestingly the MnII EPR spectrum profile appears as a fingerprint for samples coming from the same book either from cover or endleaf and it looks different for samples extracted from different books We discuss the role of EPR as a spectroscopic tool for characterizing the interaction of the ions with the paper components and as possible agents of degradationWe are deeply thankful to Dr Silvia Pugliese for providing the paper samples from Biblioteca Nazionale Marciana and for reviewing the article We are also very grateful to Prof Carlo Federici former director of Istituto di Patologia del Libro Rome for the helpful discussions suggestions and reviewing
