Karyn Posted November 1, 2022 Share Posted November 1, 2022 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. 0 Quote Link to comment Share on other sites More sharing options...
