A fantastic site to visit.
One of the things I really enjoy in YouTube is where you are able to watch short videos about a subject you are interested in.
e.g. DIY Musical instruments. There are 40 videos to watch on this subject alone.
From banjos made from biscuit tins to flutes made from different vegetables.
I think a library video that included some fun things would appeal to children along with the info on books on the subject matter and where they were available in their library system.
