Reader's Digest did it first. . .

From the London TIMES:

To howls of indignation from literary purists, a leading publishing house is slimming down some of the world’s greatest novels.

Tolstoy, Dickens and Thackeray would not have agreed with the view that 40 per cent of Anna Karenina, David Copperfield and Vanity Fair are mere “padding”, but Orion Books believes that modern readers will welcome the shorter versions.
The first six Compact Editions, billed as great reads “in half the time”, will go on sale next month, with plans for 50 to 100 more to follow.

Malcolm Edwards, publisher of Orion Group, said that the idea had developed from a game of “humiliation”, in which office staff confessed to the most embarrassing gaps in their reading. He admitted that he had never read Middlemarch and had tried but failed to get through Moby Dick several times, while a colleague owned up to skipping Vanity Fair. What was more, he said: “We realised that life is too short to read all the books you want to and we never were going to read these ones.”

Research confirmed that “many regular readers think of the classics as long, slow and, to be frank, boring. You’re not supposed to say this but I think that one of the reasons Jane Austen always does so well in reader polls is that her books aren’t that long”.

The first six titles in the Compact Editions series, all priced at £6.99, are Anna Karenina, Vanity Fair, David Copperfield, The Mill on the Floss, Moby Dick and Wives and Daughters. Bleak House, Middlemarch, Jane Eyre, The Count of Monte Cristo, North and South and The Portrait of a Lady will follow in September. Each has been whittled down to about 400 pages by cutting 30 to 40 per cent of the text. Words, sentences, paragraphs and, in a few cases, chapters have been removed.
