Description

Certified library binders are the original hardcover book binders dedicated to ensuring the highest standards in library binding in accordance with the ANSI/NISO/LBI Library Binding Standard Z39.78-2000 . Ask your certified library binder to show you their LBI Membership Certificate which indicates their membership is in good standing.

The very first attempts to establish some guidelines in this regard for our bookbinding industry go back to June 1966. The Research and Engineering Council of the Graphic Arts, working with suppliers of adhesives and large book-manufacturing plants, had uniform books adhesive bound and tested at various facilities. The results of those books tested during the first round were rated "inconclusive" and erratic. Although most of the book manufacturers used the same testing equipment, many of them had their own procedures. After a long career of testing books, I can understand why. GPO, our Government Printing Office Quality Assurance department, finally published a booklet of how to uniformly operate a tensile flex testing machine. Even to this day, when touring book manufacturing facilities, we often find Q.C. people "doing it" wrong. In conclusion, there are no Standards - only industry Guidelines, a factor that seems to be appropriate. It is important to bear in mind, that a tensile page-pull test, as well as others, individually do not measure the binding strength.
