| Abstract: | CONCLUSION. In the sample examined, a statistically significant portion of the books had centre pages weaker than the outer pages. No logical explanation for this observation has been found. The observation that the centre pages of some books are weaker than the outer pages concurs to some extent with results from accelerated aging studies of the effects of shrink wrapping on the degradation of books. This indicates that the microenvironment created within a book is such that the centre of the pile deteriorates faster than the outside regardless of whether the book is shrink wrapped or not. SUMMARIES. Artificial aging studies indicate that paper in books deteriorates faster than single sheets of paper, and that paper in the centre of a stack deteriorates faster than paper on the outside of the stack. The present study was conducted to determine if this was also true for naturally aged books. Mechanical tests were performed on paper from naturally aged books that were at least one hundred years old. The results of the testing revealed that the centre pages of a significant proportion of the books were weaker than pages nearer to the book covers. Additional chemical and physical tests have not distinguished between those books with weaker centre pages and the others. The results agree to some extent with those from artificial aging studies. |
