The 120-piece collection was gathered by a New York-based mathematician, Nicholas Falletta, who started his collection after coming across an obscure text by Carroll on logic. Much as I should regret the having to sever a connection that has now lasted nearly 30 years, I shall feel myself absolutely compelled to do so, unless I can have some assurance that better care shall be taken in future to ensure that my books shall be of the best artistic quality attainable for the money." The incident was one of a series in which Carroll and his illustrator, John Tenniel, demanded editions be changed or scrapped, including the first printing of Alice's Adventures in Wonderland. The book was amended in 34 places with notes such as "very much over-printed, very bad indeed", "very bad folding" and "paper too white, 26 pictures over-printed, 8 of them very bad". In a letter to Frederick Macmillan, the co-founder of the publisher, Carroll threatened to end his contract, under which he retained artistic control but paid all costs The Oxford-based academic wrote: "The book is worthless ... The dispute between Macmillan and its leading children's author in 1893 - the equivalent of J K Rowling threatening to pulp an edition of Harry Potter - is chronicled in a collection of Carroll documents and books to be auctioned at Christie's this month. Now they have another reason to admire him - for his iron control of his publisher.

Previously unseen letters between Carroll and Macmillan, his publisher for more than three decades, detail how the creator of Alice in Wonderland retained a complete veto on all aspects of his books. Such was the extent of Carroll's need to control that he ordered an entire 1,000-copy edition of Through the Looking Glass, his second Alice collection, to be destroyed because of the inferior printing quality. Some have been discovered in Scotland, but in England only about 30 had previously been found.. Modern authors have long had good reason to envy Lewis Carroll for the popularity of his works.

In one pit archaeologists have found a rough-out for a carved stone ball, of a type thought to have been used in ceremonial rituals Neolithic houses in England are relatively rare There are many known in Ireland. Nearby, the archaeologists have also found a much earlier settlement dating from around 1,000 years before the henges were constructed. This earlier settlement appears to have consisted of two roundhouses and a grain storage building - and this reveals bizarre evidence of prehistoric ritual practice. Inside one of the houses, archaeologists have found the remains of a human skeleton buried in a pit. It is possible that the individual - a child or teenager - was a close relative who the inhabitants of the house wanted to keep within the family, even after death. This earlier settlement - dating from 6,000 years ago - has also yielded three storage pits, probably used originally to store grain but ultimately used to contain some sort of refuse, possibly of a ritualised nature. This exciting discovery offers huge potential to improve our understanding of Neolithic ways of life in the north-east of England." The houses are 900m from the series of henge monuments - the largest of which was 100m in diameter and surrounded by banks, ditches and scores of wooden obelisks.
