I'm a big fan of libraries...just got back from picking up a book for DS.

I'm sure many people are too busy to bring their kids to the library these days and find it inconvenient. Personally, I love the whole atmosphere of libraries and took my kids often when they were growing up. I think going to the library encourages reading certainly as much as just owning a ton of books at home.
I don't blame anyone for wanting to know how the book fair (or any other fundraiser) benefits the school, and being frustrated not getting an answer.
I was never an "I'll never say no to buying a book for my child" kind of person. Kids like to buy things, and I was never one to overindulge them in a store, period. I'd often take note of something they wanted (literally...kept a little notebook in my pocketbook) and then for a holiday (including Valentine's Day and Easter, instead of too much candy), birthday or other event (graduation, last day of school), I'd look to the list, and that includes for books. I think kids just like the idea of getting something at the store, including books, whether or not they're really interested in that particular book or not.
Having said that, we always purchased from book fairs. It was a treat for them to buy books (maybe because I didn't always say "yes" every time they asked), and I considered the book fairs one of those special occasions. I also donated a book to the classroom or the library at Christmas and year end, and organized (if I was room parent) a book donation from the class at year end too. We strongly encouraged reading, in and out of the classroom, and my kids are great readers (DS not as much as the DDs, but still).
And...old books aren't necessarily "outdated". There are a lot of classics out there, that will never be "old". I also think it's wonderful for parents to share their love of particular books from their own childhood with their children. And sometimes an "outdated" book will give some great insight into "the olden days" when we were young.

I'm about to leave to donate 113 books to the Salvation Army, from when I cleaned out my elderly mom's house (and there are more I have to sort through). But I've kept a few...classics, as well "fun" ones, like the medical encyclopedia from 1946...now THAT'S interesting reading.
