We like our book club (the other students and the teacher) but the books are dumbed down. Books that they have been given a month to read are often finished in 24 hours. I think part of the problem is that the levels are not granular enough. When you have a level for 6th-8th grade, the 8th graders will be bored. I have made suggestions about more granular levels and/or a "classics" group for kids instead of all contemporary but no changes have been made. A rigorous book club of classics would definitely draw us in.
We would go to a "how to use the library's resources" class. It wouldn't even have to be electronic. Just finding out what reference books are available, meeting a friendly reference librarian, an intro to cataloging techniques, etc would be nice. I do teach them those things, but I'd love a class to make sure I'm not missing anything.
We like the leave a magazine/take a magazine box for library visitors to exchange with each other.
We don't volunteer. I'm too busy and the kids are too young but it's something my DS has talked about for the future. I could see him wanting to be the contact person for a book club. And we support the friends of the library through food and book sales.
