As of the latest update to this page on 17 August 2017, the encyclopedia contains 17,232 entries totalling 5,413,094 words. There are 193,360 internal hyperlinks between entries, corresponding to cross-references in past book editions. (At this third edition's launch in October 2011, the figures were 12,230 entries, 3,222,920 words and 113,492 hyperlinks.) For comparison, the second print edition (1993) had 6571 entries totalling 1,311,108 words, with 41,712 internal cross-references; the slightly expanded CD-ROM (1995) had 6732 entries totalling 1,378,261 words, with 43,302 internal links. The first edition (1979), assembled without the help of word processors, ran to 3574 entries and an estimated 730,000 words; no one has been able to face counting the internal cross-references.
The entry count for each edition includes many cross-reference entries which may have little or no actual content but refer readers to other entries where their subject is covered. Many of these cross-references are author pseudonyms such as "French, Paul / Pseudonym of Isaac Asimov." or variant titles of films and television series; see Editorial Practices for more. The entry count breaks down to 2865 full and 709 cross-reference entries in the first edition; an estimated 4360+ full and 2100 cross-reference entries in the second edition; 4530 full and 2202 cross-reference entries in the CD-ROM edition; and 12,230 full and 5002 cross-reference entries in the current state of this third edition.
Of the major contributors, John Clute continues to lead the pack with 6502 entries written solo and 1235 more in collaboration, many of the former (he wishes to emphasize) being short, and the latter generally being updates to already existing entries. The entry-count figures for other contributors of 20 or more solo entries (either at the time of this edition's launch in October 2011 or subsequently attained), with joint-credit counts added in parentheses, are:
In terms of approximate word counts, the leading contributors are John Clute with over 2,444,000 words, David Langford with 566,000, Peter Nicholls with 450,000, Neal Tringham with 243,000, Brian Stableford with 175,000, Mike Ashley with 152,000, Geoffrey Stevens with 151,000, Jonathan Clements with 133,000, Gary Westfahl with 105,000, Nick Lowe with 74,000, Malcolm Edwards with 70,000, John Brosnan with 42,000, Adam Roberts with 40,000, John Grant with 37,000, Mathew Downward with 35,000, John Eggeling with 30,000, John-Henri Holmberg with 30,000, Abigail Nussbaum with 30,000 and Konrad Walewski with 21,000. All figures are rounded down to the nearest thousand, with a threshold for inclusion in the above list of 20,000 words either at the time of this edition's launch in October 2011 or subsequently attained.
In the preparation of the above "league tables" credit is given for each separately signed section within large omnium-gatherum entries like Batman Films and Tarzan Films, which seems only fair. Collaborative entry or entry section word counts are shared equally among contributors to that entry or entry section.
For the sake of sanity, this "Statistics" entry is not necessarily updated for every small change or correction to the encyclopedia's text. However, the report of the total number of images in the Picture Gallery archive is automatically updated on that page [see links below] whenever new material is added. [DRL]
