The INTERNET Database of Periodic Tables
There are thousands of periodic tables in web space, but this is the only comprehensive database of periodic tables & periodic system formulations. If you know of an interesting periodic table that is missing, please contact the database curator: Mark R. Leach Ph.D. The database holds information on periodic tables, the discovery of the elements, the elucidation of atomic weights and the discovery of atomic structure (and much, much more).
Periodic Tables from the year 1995 :
| 1995 | Chemical Helix Periodic Table |
| 1995 | Live! Periodic Table |
| 1995 | Melinda Green's Periodic Fractal of The Elements |
| 1995 | Klein's Periodic Table of The Elements |
| 1995 | Considine's Polar Periodic Table |
| Year: 1995 | PT id = 45, Type = formulation 3D spiral |
Helical Periodic Table
Tarquin Publications sell a make-your-own three dimensional, helical periodic table.
| Year: 1995 | PT id = 118, Type = data |
Periodic Table Live!
A good site with lots of infomation, pictures & video clips, here:
| Year: 1995 | PT id = 241, Type = formulation spiral |
Melinda Green's Periodic Fractal of The Elements
Melinda Green writes: "This is an alternative version of the standard chemistry Periodic Table of the Elements that I developed. In high school I learned the basic concept of element families and how they were arranged into columns to show the periodicity in their electrical properties. I was fascinated with the idea, but immediately wondered whether there might be better ways of graphically showing those relationships." read lots more here

Klein's Periodic Table of The Elements
Klein DJ, Similarity and Dissimilarity in Posets, Journal of Mathematical Chemistry, 18(2), 321–348 (342) (1995)
The relevance of partially ordered sets (or posets) in a wide diversity of contexts in chemistry is emphasized, and the utility of distance functions (or metrics) on such posets is noted. First a notion of "scale similarity" is introduced to make comparisons within certain so-called "scaled" posets, for which there is formulated natural "comparators", which in turn lead to associated distance functions. Beyond taking note of several chemically relevant examples of these "scaled" posets and their consequent associated similarity measures, a second chemically relevant class of so-called "shifted" posets is similarly developed, with examples. Even further extension of some aspects of the current approach is indicated, and finally the multi-posetic character of chemical periodic law is suggested.
Thanks to René for the tip!

Considine's Polar Periodic Table
From: Considine DM (ed.) 1995, Van Nostrand’s Encyclopedia of Science, 8th ed. New York, p. 2376
René Vernon writes:
"A nice design but of quite limited practical utility for quick reference or detailed chemical analysis."
