Aside from adding categories to our books, as many of you are hearing me talk about a lot, we decided to also include a time stamp. We made color coded labels for different eras. Our era decision was based on the number of books we had. For example, We have a lot of books that cover the decades in the 1900s but a lot less that cover the era before Christ, so, we mixed a lot of years. We are labeling each book with the color coded labels (we just used an address label template, filled each label with a lot of text and printed it on colored paper). When kids come in looking for a specific era, we can share the color coded label with them and say... look for this label. If they come in looking for a specific situation (like the Revolutionary War) we can guide them to that specific area.
Yes, it took a lot of time. Yes, it took a lot of energy and brainstorming. Yes, I have gotten some slack from veteran teachers and librarians who think Dewey is God. Yes, I have people questioning what I have done. I don't care. Because it my eyes, I am doing this for kids and for that, it is worth it.
