For the last fifty years , library binders have employed a standard endpaper construction for all of its bindings. Now, because of new binding techniques and the deterioration of paper some preservationists have placed a demand on library binders to develop an alternate endpaper construction. The purpose of this study was to determine the hinge strength and openability performance of the two most conmon library binding techniques, oversewing and Singer side sewing, which were flat backed and rounded/backed in relation to the currently used the LBI Standard endpaper as compared to the wide-hinged endpaper construction. It was questioned if there would be a significant strength difference between the two endpaper constructions: wide-hinged vs. the LBI Standard. If there were differences, it was further questioned if they were related to the paper which was used. Three tests were utilized in response to these questions: 1) the Instron Hinge-Pull Test, 2) the UBT Tumble Test, and 3) the Tumble Test. These tests provided the data required to analyze the comparisons via the ANOVA Analysis and the Duncan Multiple Range Test. Through these analyses, it was statistically determined that the tested that endpapers were significantly different Vlll in hinge strength at a 99% confidence level. These statistics also determined, early in the testing procedures, that the relationship of paper and grain direction had no significant value in the determination of hinge strength or openability of a book. It was also questioned if there would be a significant difference between the two endpaper constructions: wide-hinged vs. the LBI Standard, in reference to openability. If there were differences, it was further questioned if they were related to the paper which was used. A Photocopy Openability Test was developed to investigate these questions. The data was measured to the nearest 1/64" and applied to the ANOVA analysis and Multiple Range test. At a 99% confidence level it was determined that the endpapers were statistically different and that the wide-hinged endpaper provided a greater area of openability in all binding techniques.
