by IAPSOP was formed in late 2009, when it became apparent to IAPSOP's founders that (a) the repository libraries traditionally expected to retain Spiritualist and occult periodicals were in many cases removing these from circulation, or from their collections entirely; (b) that independent students and researchers were in some cases duplicating effort and expense to have materials preserved digitally, largely for their private use; and (c) that digital libraries like Google Books were completely indifferent to the special curatorial problems of periodical literature generally, and occult literature in particular.

The IAPSOP Archives are maintained by an informal collective of students, academics and researchers with an interest in the periodical literature of Spiritualism and the occult, for the purposes of preserving the substantial body of Spiritualist and occult periodical literature produced between the 1840s and the start of the Second World War. These materials are provided in curated, digital form, already indexed, suitable for online reading, scholarly use and citation.
