  I review the current status of studies of the large-scale structure of the
Universe using redshift surveys of galaxies and clusters of galaxies. I first
summarise the advances we have made in our knowledge of the cosmography of the
z<0.2 Universe during the last 25 years, as well as the status of the major
surveys in progress. The question of how the "a priori" selection of some
classes of objects "biases" the mapping of the underlying mass density field is
discussed in some detail. I then emphasise the advantages of using clusters of
galaxies selected in the X-ray band as tracers of large--scale structure,
summarising the most recent results of the REFLEX survey, which is under
completion. The strong potential of using X-ray clusters to study the evolution
of structure to large redshifts is underlined. I then summarise some of the
most recent statistical results on the clustering of galaxies and clusters,
using the two-point correlation function xi(s) and the power spectrum P(k). In
particular, I concentrate on the increased information available on the
detailed shape of these functions on large scales, lambda~100/h Mpc. I argue
that significant evidence is accumulating from different observations that P(k)
has a well-defined and possibly narrow peak around k~0.05 h/Mpc. I conclude
with a glimpse into the future of large-scale structure surveys at high
redshifts, describing the features of the VIRMOS deep survey, which will soon
start collecting redshifts with the ESO VLT for ~150,000 galaxies at a typical
depth of z=1.
