This applies to the release of information to the parents’ of minors when the minor has their own library card. The Supervisor of the Public Records of the Commonwealth of Massachusetts, Carolyn Kelly MacWilliam, stated in May 1997, “A public library may not disclose records which reveal a minor’s borrowing information to the minor’s parent, regardless of whether the parent is paying the fine on an overdue item or the parent has signed the child’s library card application form.” I wonder if that's really enforced. Most libraries are pretty informal places. It doesn't seem like the situation would come up very often or that librarians would know what to do about it. It sounds more like a rule for rule's sake, rather than the actual procedure.
Take in the context of the article. I'm sure the rule is strictly enforced and anyone in the library who revealed a minor's borrowings to his/her parents would be punished.
I spent a few years in the area and am not surprised at their ultra-morally superior attitude.
BTW: I went in my local library last week.
The 20 or so computer consoles were all occupied. But the stacks were empty of people.
I suppose soon if something isn't on electronic media it might as well not exist.
