It has built up a history library, comprising 4,000 books, 3,000 photographs, 5,000 postcards, posters, videocassettes, and historical maps. It publishes its research work with periodic exhibitions illustrating the historical continuity of Thessaloniki and the wider area of Macedonia, organizes conferences and lecture series, and hosts events organized by other institutions with related interests. The History Centre also produces a scholarly journal titled Thessaloniki, containing original scholarly articles, and books on Thessaloniki and its history.

The Thessaloniki metropolitan area or larger urban zone (LUZ) is the complete area covered and directly influenced by Thessaloniki. The metropolitan area traditionally consisted of the municipality of Thessaloniki and its immediate surroundings, what is today referred to as the Thessaloniki urban area. However, since the mid to late 1990s, the areas surrounding the urban area, have succumbed to urban sprawl and what used to be agrarian communities are rapidly urbanizing and being developed into suburbs or exurbs. This is creating new problems for a region already facing issues such as pollution, traffic congestion and social ills. Thessalonians usually refer to 6 municipalities and 1 municipal unit as the "City of Thessaloniki" (or the Thessaloniki urban area); this is the contiguous densely built-up urban area of the city. However, the metropolitan area also includes the city's immediate surroundings, adjacent zone of influence and its low to medium density suburbs that surround the densely built-up urban area. Thessaloniki spreads over 30 kilometres (19 mi) from Oraiokastro in the north to Thermi in the south.
