Key Information

History

[edit]
Malcolm Edwards, John Clute and Peter Nicholls discussing the early days of The Encyclopedia of Science Fiction at Loncon 3, Worldcon 2014

First edition

[edit]

The first edition, edited by Peter Nicholls with John Clute,[1] was published by Granada in 1979. It was retitled The Science Fiction Encyclopedia when published by Doubleday in the United States. Accompanying its text were numerous black and white photographs illustrating authors, book and magazine covers, film and TV stills, and examples of artists' work.[2]

Second edition

[edit]

A second edition, jointly edited by Nicholls and Clute, was published in 1993 by Orbit in the UK and St. Martin's Press in the US. The second edition contained 1.3 million words, almost twice the 700,000 words of the 1979 edition.[3] The 1995 paperback edition included a sixteen-page addendum (dated "7 August 1995"). Unlike the first edition, the print versions did not contain illustrations. There was also a CD-ROM version in 1995, styled variously as The Multimedia Encyclopedia of Science Fiction and Grolier Science Fiction.[4] This contained text updates through 1995, hundreds of book covers and author photos, a small number of old film trailers, and author video clips taken from the TVOntario series Prisoners of Gravity.

The companion volume, published after the second print edition and following its format closely, is The Encyclopedia of Fantasy edited by John Clute and John Grant.[4]

Third edition

[edit]

The third edition was released online in October 2011, by SFE Ltd in association with Victor Gollancz, Orion's science fiction imprint,[5] with editors John Clute, David Langford, Peter Nicholls (as editor emeritus until his death in 2018) and Graham Sleight.

The encyclopedia is updated regularly (usually several times a week) by the editorial team with material written by themselves and contributed by science fiction academics and experts.[1] It received the Hugo Award for Best Related Work in 2012. Though the SFE is a composite work with a considerable number of contributors, the three main editors (Clute, Langford and Nicholls) have themselves written almost two-thirds of the 5.2 million words to date (September 2016), giving a sense of unity to the whole.[4]

Fourth edition

[edit]

The Encyclopedia ended its arrangement with Orion in September 2021 and moved to a new, self-owned web server, resulting in the launch of the fourth edition in October. While based on the earlier design, the new edition incorporates a number of revisions; for instance, many author entries now include thumbnails of the author's book covers, randomly selected from the relevant Gallery pages.[6]

Contents

[edit]

The Encyclopedia of Science Fiction contains entries under the categories of authors, themes, terminology, science fiction in various countries, films, filmmakers, television, magazines, fanzines, comics, illustrators, book publishers, original anthologies, awards, and miscellaneous.[7]

The online edition of The Encyclopedia of Science Fiction was released in October 2011 with 12,230 entries, totaling 3,200,000 words. The editors predicted that it would contain 4,000,000 words upon completion of the first round of updates at the end of 2012; this figure was actually reached in January 2013, and 5,000,000 words in November 2015.[8]

Reception

[edit]

Writer Ian Watson reviewed the first edition in 1980, the journal Foundation. Watson noted his positive surprise that the publication contains much smaller amount of errors than expected, and noted that its format allows for easy correction of those in the expected second edition. He concluded that the "volume is a genuine encyclopedia - the first such. It is the Britannica of the sf field", positively commenting on the breadth and scope of the entries, and even the illustrations, which are informative, and not just decorations.[9]

Edward James, a British scholar of medieval history and science fiction, praised the second edition of the encyclopedia in his review (also for the journal Foundation) in 1993, writing that it is "the one indispensable volume on every sf readers' shelf: not only the best reference work in the field, but one of the best reference works I have seen in ''any'' field". He did, however, found the "sneering" tone of some film entries (de facto film reviews) less than ideal for an encyclopedia. James also noted that although the project is a collaborative effort, nearly half of the entries for that edition have been written by Clute, which he saw as a very impressive achievement on his part.[2]

Writer Gary Westfahl also reviewed the second edition, for the journal Extrapolation. He called it "an invaluable compendium of and contribution to fifty years of science fiction research", representing "a true conceptual breakthrough" for the field of science fiction studies, and noted that even more than the encyclopedia's previous edition, this one "is the one essential reference book for anyone interested in science fiction". He also predicted that "this work will justifiably be cited in all studies of science fiction during the next decade, and those studies will be significantly better because of Clute and Nicholl's painstaking work". Nonetheless he noted that the volume is not perfect, and contains some errors as well as several entries on novel topics that could use more grounding in prior research before being written about in an encyclopedia".[10]

Nicholas Ruddick briefly commented on the second edition, noting that it has been "highly praised".[11]

Briefly commenting on the third edition, Andrew M. Butler called it "a gold standard for reference works in the field".[12]

The encyclopedia also received several other reviews, by writers and scholars such as Gary K. Wolfe, Don D'Ammassa and David G. Hartwell.[13]

Development and Editions

Origins and First Edition

The Encyclopedia of Science Fiction was conceived in 1975 by Australian critic and editor Peter Nicholls, who envisioned it as a comprehensive reference guide covering literature, key authors, major themes, and related cultural elements. Nicholls, then serving as editor of the Foundation journal for the Science Fiction Foundation, organized a 1975 symposium that helped shape the project's scope, drawing contributions from prominent figures in the field. The first edition was published in 1979 by Granada Publishing in the and Doubleday in the United States, comprising a single illustrated volume of 672 pages with approximately 2,800 entries totaling over 700,000 words. Nicholls served as General Editor, with John Clute as Associate Editor responsible for much of the literary content. Key features of the edition included in-depth essays on science fiction subgenres, recurring themes such as and dystopias, and historical overviews tracing the genre's development from its 19th-century origins through the late , supported by illustrations like author portraits and magazine covers. Entries provided critical analysis alongside basic bibliographic details, including publication histories for works and authors. The initial scope was limited primarily to English-language science fiction, reflecting the era's available scholarship and resources, with entries emphasizing prose literature over film or other media and offering foundational rather than exhaustive coverage. This print edition laid the groundwork for subsequent expansions that addressed these constraints.

Second Edition and Expansions

The second edition of The Encyclopedia of Science Fiction, published in 1993 by in the UK and in the , represented a substantial revision and expansion building on the foundation of the 1979 first edition. Co-edited by John Clute and Peter Nicholls, with as contributing editor and John Grant as technical editor, it increased the number of entries from approximately 2,800 to over 4,360, while the total word count grew from around 730,000 to approximately 1,300,000 words. This overhaul involved rewriting and updating existing entries to incorporate developments in science fiction through the and early , alongside the addition of roughly 2,100 entries for improved navigation. Key enhancements included broader coverage of international science fiction authors and works, reflecting a more diverse editorial team that spanned Canadian, Australian, English, and Scottish contributors, with about 85% of the content authored by Clute, Nicholls, and . The edition also featured expanded thematic essays and terminology entries to provide deeper conceptual analysis of genres, motifs, and cultural impacts within .

The result was a total of 1,378,261 words across 6,731 entries, enhanced by 43,000 internal links and separate essays or book synopses not integrated into the main alphabetical structure. For the first time, the encyclopedia became fully searchable in a digital format, enabling rapid access and elements, though it retained the core text from the print edition.
