There was a boom in symmetry related basic monographs in the years 2007-2009.
These publications together mark a milestone in the process of disciplinarization of symmetrology.

Over the listed scientific monographs there were published a few further books recently that made a good service for the popularization of symmetry studies in the wide public and among pupils and undergraduate students:
Avner Ash and Robert Gross: Fearless Symmetry, Princeton University Press (2006)
Mark Ronan: Symmetry and the Monster, Oxford University Press, New York (2006)
Mario Livio: The golden ratio and aesthetics (2002)
I have the pleasure to announce the publication of a booklet with full colour photographs of hats woven with palm leaves. You may see beautiful shapes, curves, spirals, polygons, designs and patterns, and attractive symmetries…
From the introduction:
This booklet “Hats from Mozambique” presents photographs of woven hats I have collected since the 1980s from four coastal regions of Mozambique: the districts of Palma and Mecúfi in the Cabo Delgado Province in the North, and the districts around the Bay of Inhambane and the Manjacaze District in the Gaza Province in the South (see the map on page 9). Some of the hats presented here, like the ones from Palma and the hats from Inhambane decorated with band or plane patterns, are exceptional and very rare…
I trust that the photographs may convey an impression of the beauty and diversity of hats made in Mozambique, and of the creativity and imagination of the women and men who weave them.
The book "Hats from Mozambique – Chapeus de Mocambique" (ISBN 978-0-557-38758-80), published by the ‘Associacao Indico’ (Maputo), is available both in print and as download from www.lulu.com at http://stores.lulu.com/pgerdes (52 pages).
Please, forward to those who may be interested.

African Basketry: A Twill-Plaited Designs and Patterns
by Sergey V. Petoukhov (in Russian)
This book describes the utility of matrix methods to represent and to analyze hierarchical systems of genetic encoding for mathematical classification and for modeling natural forms of ordering these systems. The work demonstrates a connection of forms of ordering genetic code with special algebras, and also with a series of other well known mathematical structures: Hadamard matrices, double numbers, transformations of hyperbolic
turns, the golden section, the Pythagorean musical scale, etc. These algebras (e.g., that of quaternions) are related to special multidimensional geometries. They permit to develop new models in the fields of molecular genetics, bioinformatics and mathematical biology in general.
The received data reveal adequacy of matrix mathematics from the theory of discrete signal processing and noise-immunity coding to investigate molecular systems of genetic encoding. They give additional bases to think that structures of genetic code are determined in many respects by demands of noise-immunity of genetic information.

There are some chapters in the book which refer explicitly to symmetry: they are chapter VII (Symmetry in finite words and
in languages (p.219-250) and the section “Symmetry phenomena in infinite words (p.365-372). But there are many other chapters referring to symmetry phenomena under some specific forms, such as periodocity and its extensions, (almost periodicity, quasiperiodicity), attractors,etc.:chapter IV, Numbers as words (p.127-154), chapter IX, Infinite words (p.337-380), chapter X, Biology and languages(p.381-432), and chapter XI, Chemistry and languages (p.433-448) are in this situation.The other chapters too have strong links with symmetey phenomena.
