When me and my bro were still little kids, our father often spent much of the week travelling around the country [inspecting sub-contracts for a firm that built mechanical handling plant].
I already was reading almost anything put in front of me, but little bro was less enthusiastic.
So, in an attempt to bolster his skills, Dad would bring him the next one - or two - in the learn to read series.
To reduce the sibling rivalry, I got something like the birds of the seashore, or a how it works.
Eventually, as bro's reading improved, we were both getting the more informative ones [although I sometimes got an "Armada" paperback instead]
They are currently on the top shelf in the library / dining room at my brother's house [which was Dad's] from memory, I would say there's something like 8 or 9 feet of them !
Before Dad died, I had given him a few of the modern "piss-take" ones, mostly to make him laugh !
I did interview the woman who runs ladybird fly away home some years ago though for my podcast.
