The Web version of the Encyclopedia of Aikido is essentially the same as the original edition published in 1991. It does contain a number of minor updates mainly involving changes in rankings, personal details, factual additions, and death dates for those who have passed on since the book was first published.
At the present time, the author is not regularly updating the Encyclopedia and has no definite plans to do so. We believe the book still has considerable value since much of the content is of an historical nature and is therefore not subject to change. Anyone consulting the Encyclopedia of Aikido should keep in mind the date of publication — 1991 — and the fact that changes will not be forthcoming anytime in the near future.
If readers do wish to submit corrections, additions or suggestions to the author, they will be accepted and filed for future reference with the understanding that they may not be acted upon immediately.
