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).

Wrigley's Lamina System
In two papers: A.N. Wrigley, W.C. Mast, and T.P. McCutcheon, "A Laminar Form of the Periodic Table, part 1," Journal of Chemical Education 26 (1949): 216-218 and A.N. Wrigley, W.C. Mast, and T.P. McCutcheon, "A Laminar Form of the Periodic Table, part 2: Theoretical Development, and Modifications," Journal of Chemical Education 26 (1949): 248-250 a Laminar Periodic Table is introduced. (Thanks to Ann E. Robinson for this informaton & references.)
This formulation was discussed and re-drawn by van Spronsen in 1969:
There is a Russian publication "100 Years of Periodic Law of Chemical Elements", Nauka 1969. On page 87 there is a formulation that appears to be a version of the van Spronsen re-drawing. The caption says: "Volumetric Model of 18-period Long System of D.I.Mendeleev." after Riggli (1949). (Thanks to Larry T for this.)
