For those interested, the latest issue of THE NEW LIBRARY SCENE, April 1992,
has some interesting articles on binding.  Specifically, some of the more
in depth topics discussed (for those interested) are "to trim or not",
pulling ads, 1986 LBI standards, rounding and backing, etc.

An interesting journal for those involved in binding (we just recently
renegotiated our binding contract and tried to do some extensive research
in this area).
