International Association for the Preservation of Spiritualist and Occult Periodicals


The IAPSOP is a US-based private organization focused on the digital preservation of Spiritualist and occult periodicals published between the Congress of Vienna and the start of the Second World War.

Our all-volunteer staff digitizes, indexes and makes available free-of-charge these periodicals, in our archive, for use by students and researchers.

We have a standing want list and will respond promptly to inquiries and offers from sellers.

We accept contributions of material and labor to further this work.
