The PFF's collections now number over 45,000 artifacts, covering all the branches of study relating to modern Greek culture, with the emphasis on ethnography, fashion, and children.

In order to improve the management of the collections, the "Aristeides" programme for electronic documentation was created, and designed from the outset on the basis of the expertise of the Peloponnesian Folklore Foundation. This programme is already being used not only by the PFF, but also by a number of museums.
