Data on ferroelectric and antiferroelectric behaviour of pure compounds and solid solutions are critically evaluated and in addition all other properties relevant to the characterization of these crystals are presented in tables and figures. Subvolume A is for oxides and B for non-oxides including liquid crystals. This subvolume consists of a printed version and an electronic version on CD-ROM. All the compiled data can be found on the CD-ROM. The abundance and diversity of the data, however, make an overview of the relevant research field difficult, and thus the printed version is designed...
