You can find many of these informative, interesting, eye-opening books in most libraries and bookstores such as Flourish and Blotts - Diagon Alley, and Spellbound Books - Hogsmeade.

Buying, Selling, and Trading House-Elves by Ignatious P. Ironheart. Witness first-hand how house-elves are considered a commodity! Horrifying book, though very useful in case you are interested in buying a house-elf from someone and setting him free!

Effective Punishments for Not So Very Effective Elves by Quentin Quincy Quimby. An appalling index of extremely overly-imaginative punishments for a house-elf who "misbehaves." How anyone can deny that house-elf abuse exists when this book exists is beyond me. I personally don't see how Effective Punishments cannot be banned from places that are not located down Knockturn Alley.

Hogwarts, A History. Though, of course, this is a book which is not entirely reliable in providing an unbiased account of the house-elf staff at Hogwarts. A Revised History of Hogwarts would be a more accurate title. Or A Highly Biased and Selective History of Hogwarts, Which Glosses Over the Nastier Aspects of the School. Not once, in over a thousand pages, does Hogwarts, A History mention that we are all colluding in the oppression of a hundred slaves!

Pumpkin Soup For The House-Elf's Soul by Bonnie Bipkinney and Jiffy the House-Elf. A wonderful gift for any house-elf, full of inspirational stories that will touch you, too.

Why House-Elves Make Brilliant Baby-sitters, an article which appeared in Wizarding Life in 1979, by one W.C. Waterloo. Here is the undeniable proof of the great intelligence and sensitivity of house-elves, though they really ought to be paid for their baby-sitting, don't you think?

Yes, Sir! A Guide To House-Elf Etiquette by Swotty the House-Elf. This is a perfect example of the extent to which house-elves have been brainwashed! A most excellent guide to learning how the carefully conditioned minds of these poor creatures work.
