The recent efforts to digitise plates in astronomical plate archives and to access these valuable and unique data by powerful computers and newly designed software enable to consider sky surveys based on these huge (there are almost 3 millions of astronomical archival plates at different observatories) database. I will review the recent status of astronomical plate collections as well as recent efforts to evaluate and scientifically exploit these data. The main advantage of the astronomical archival plate collections is the very large and unique time coverage which can span over more than 100 years and can achieve fine limiting magnitudes . As for scientific astrophysical applications, I will review astrophysical applications of these data and will show some selected examples. Since some parts of the sky are covered by very numerous and high-quality archival plates, there can be projects proposed based both on modern satellite data as well as on archival plate data. The optical identification of newly detected gamma-ray sources e.g. by the ESA INTEGRAL satellite can serve as an example, since most of these sources are located in regions either close to the Galactic centre or to the Galactic plane area which were densely covered in the past by several plate programs such as Franklin Adams Fields in Leiden proposed by Prof. Hertzsprung, or Sonneberg Field patrol proposed by Prof. Hoffmeister. These analyses require newly designed software whose examples will be also presented and discussed.
