I used to work at Chapters for almost ten years so yeah my book collection for myself and my son is quite extensive. I have bookcases throughout our house in different rooms. In my main playroom I have one bookcase that has craft supplies, books I read for Storytime on higher shelves and then the lowest shelf has some more sturdy books. Also in my living room our coffee table has a shelf underneath that I have sturdy bins that hold the majority of our board book collection which my son loves to have easy access to at different times of the day. So I definitely will continue to have the more sturdy books accessible to everyone at any point but the books I truly treasure only I have access to them to supervise their use. I was considering getting the cloth sling bookcase but upon reading the post about it I may reconsider, my bins of books seem to be working just fine anyway.
I have a rule the bookcases I own are all I'm allowed to have so if they are all full before I can buy anymore books I have to get rid of some books to make room. It has somewhat curbed my crazy book addiction until that is I got my kobo. hehe don't ask me how many ebooks I have now for myself. lol
