These are now listed separately on their own pages
Published 26 September 2019. This series of 12 monographs, contain much of the material from my Knight's Tour Notes web-pages. It was orignally proposed to publish it in book form but has proved too much to reproduce that way.
I produced Volume 1 of 8 issues starting in 1990. Volume 2 of 12 issues was continued by Peter Wood. Subsequently it became the magazine of the British Chess Problem Society and ran to 8 volumes and 64 issues up to 2010. A volume was edited by myself, two volumes by Paul Byway and three by John Beasley.
This was issued in two printed volumes and then went online: Volume 1 was of twelve issues (1987-1989) and Volume 2 of six issues #13 - #18 (1996-2001).
The online Volume 3 ran to 27 issues, usually each of five topics, #19 - #45 (2001 - 2010).
Directory of Numbers

This is a 24-page list of all numbers up to 999 and then all numbers up to 9999 not ending in 0, 2 or 5.
It indicates whether a nunber is Prime or else shows its prime factors and their powers.
To factorise four-digit numbers ending in 0, 2 or 5 divide by 10, 2 or 5 and look up the smaller number resulting.
The Learian Limericks
A PDF version is now (22 July 2013) available.
Simple Chess Variants
This 14-page A4 booklet was compiled for a talk I gave on 21 August 2010 at the Hastings and St Leonards Chess Club.
It is based on the notes on Chess Variants page but deals only with variants that can be played using normal board and pieces.
Exact Echoes
— by G. P. Jelliss — July 2010 — file size: 1.67 MB.
This 50-page A4 booklet derives from the successful ‘Exact Echoes Tourney’
which was announced in Chessics issue 15 in 1983, entries being published
in issues 17 to 21 and the award in issue 23 in 1985. Composers were asked to
send in not only their original compositions but also outstanding examples of
their previous work, or the work of others that they considered should not be
missed, with a view to publishing a booklet on the subject. Twenty-five years
on I can now publish the collection in electronic form (as a PDF), but I have
not so far attempted to bring the collection up to date to cover work done in
the intervening years.
Figurate Numbers
— by G. P. Jelliss — June 2008, with additions November 2008 — file size: 1.39 MB.
This 16-page A4 booklet is an account of numbers that can be represented by
counters arranged in various geometrical formations. This is work in progress,
and I hope to issue an extended version when further work has been completed.
It includes tables of all numbers from 0 to 999 with their prime factors and
details of their shapes. Particular emphasis is placed on numbers that can be
presented in two different shapes.

This offshoot to my knight's tour studies is a 22-page A4-size booklet

Retro-Opposition, and Other
Retro-Analytical Chess Problems by T. R. Dawson — edited by G. P. Jelliss
