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.
If you want a complete local copy of IAPSOP's holdings, follow these instructions.

|Service Degradation Notice|
|Patrons may notice that at times the site appears to respond slowly, and documents take a long time to download.
The IAPSOP web site is currently being misused by actors on the Internet, attempting to copy the entire site (which is fine) using webcrawler/webcopier software (which is not fine), for some unknown purpose.
When we detect these actors misusing the site, we limit the total bandwidth available to the site, which tends to dissuade the bad actors, but unfortunately affects our patrons as well.
If you wish to obtain a copy of IAPSOP's holdings, please follow these instructions.
We apologize for the inconvenience.
