I found this online and could definitely relate, as will anyone who collects children's books that are mostly out-of-print ...
The Collector’s Nightmare
(Tune: This Old Man)
What to choose? Can’t pick one!
Now my nightmares just begun!
There are Blyton, Oxenham,Needham and Jane Shaw,
Fairlie Bruce and many more.
Can’t afford to buy two,
Children’s Press will have to do!
‘Cause there’s Compton,
Buckeridge, Streatfield and the rest,
Have to settle for second best.
On the shelf I’ve found three,
Which one is the one for me?
I’ve found Bunter, Ballet Shoes,
Biggles and beyond,
Bobbsey Twins and Michael Bond.
Catalogues? I’ve had four,
Can’t stop sending off for more.
They’ve got Ransome, pony books,
Forest and Brazil,
Courtney, Johns and Lorna Hill.
Tolkein, Famous Five,
Won’t come out of this alive!
All my shelves are full, but I cannot
seem to stop,
I keep buying out the shop!
