Abstract. Digital stacking of Schmidt Plates greatly increases the depth of the data allowing detection of galaxies at ~z ~ 1. We can probe the angular correlations of galaxy and cluster positions over scales of ~ 500/i -1 Mpc. Radial distance information can be obtained by identifying radio galaxies in the field and using their "standard candle" properties. A search for cosmic string effects, beginning with the stacked dataset, has now been extended to ~ 100 equatorial J-plates.
