Penguin paperbacks have long provided readers with authoratative editions of classic literature from all nations and genres, edited by experts in the field. Peguin regularly updates its classics, with new translations, new citations, new editors and different covers. Thus Penguin’s Science Fiction Omnibus, published in Britain in November 2007, updates the Aldis edited SF Omnibus of 1973.
You can compare the 1973 edition’s Table of Contents
here with the Table of Contents for this new 2007 edition here. 
A thoughtful consideration of SF sparked by this new edition of Aldis’s Omnibus appears in the current Times Literary Supplement.
You may not agree with every point Dinah Birch, the writer, makes, but its interesting to read.
[ Loneliness shadows science fiction, and is made more acute by its customary settings amid the emptiness of space, with solitary voyagers or beleaguered bands of adventurers encountering the hostilities of planets that deny the consolations of familiarity. The opening images of Walter M. Miller’s brilliant “I Made You” (1954) are typical:
"It sat on the crag by night. Gaunt, frigid, wounded, it sat under the black sky and listened to the land with its feet, while only its dishlike ear moved in slow patterns that searched the surface of the land and the sky The land was silent, airless. Nothing moved, except the feeble thing that scratched in the cave."
The “feeble thing” turns out to be a man, about to be destroyed by the suffering robot that he has created. The story is recognizably a reflection of Frankenstein. It serves, like Frankenstein, to caution against the dangers of scientific progress pursued with no thought of moral consequences. This bleakly admonitory tone repels many readers. It is the business of science fiction to alarm, in the sense of providing the excitement of thrilling dangers, and of scaring readers with the prospect of a future in which human values are threatened. Ruthless invasions, apocalyptic plagues, wars and famines, dying stars, mechanized intelligences and predatory civilizations, have been its favourite devices. Fredric Brown’s “Answer” (1964), a piercingly brief story, points to the hazards of the internet, years before it was invented. Scientists link every computer on earth in order to ask a single question – “Is there a God?”. The answer is immediate: “Yes, NOW there is a God”. The warnings of science fiction are endlessly inventive, often witty, and sometimes salutary, but they do not make for comforting reading. ]
When I was a tad, far back in the days when there was little if any SF and even less F on television and in the movies and in the bookstores, these anthologies and omnibuses were among my most prized discoveries for reading, and re-reading, and re-reading even more times than that. I didn’t realize it, but these kinds of collections were teaching me what was good about SF, and how it worked, through an infinite variety of treatments and approaches, only limited by the number of stories and writers that could be included.
