Breadth of knowledge

Most read to some extent, a lot forgotten. This is the mainly educational bookshelf that I will use for the Wide Wednesday education theme.
You may notice this is actually 3 shelves of the bookcase stacked side by side to make it look expansive! A fair bit of fiddling needed.
Not all are educational either.
Thanks StevenG for hosting.
edit. Something funny with the upload yesterday.So removed and re-added to see if that fixed it.
