The archival management system which was developed after the unification of Buda, Pest and Óbuda country town, was based on the principles laid down in the former period.

[1] The archival tasks were already performed by an independent organ, but its main duty was still a record office type work.

At that time the general assembly of the city made a conceptual decision that searching and making available the sources in the Archives must be placed at the centre of its activity.

The circumstances improved at the turn of the century when the repositories - that were previously dispersed - were moved to the building of the Central City Hall.

[1] The Budapest City Archives keeps 36000 linear meters of documents, preserves and delivers them for researchers and customers in the new building which possesses 23440 m2 of net area.

The database system of Budapest City Archives contain millions of records and continue to expand.

The strong point of the latter is the Joint Search option and the advanced handling of images (including pdf format, geo-referenced historic maps, etc.).

The databases make accessible mainly the data contained in sources that can help us find out more about the residents of Budapest, our built environment, visual information and the socialist period.
