Among the many publications and initiatives of the Esperantic Studies Foundation is the periodic journal Informilo por Interlingvistoj, now available in English translation as Information for Interlinguists. Both are published in cooperation with the Center for Research and Documentation on World Language Problems.

IfI/IpI covers news from the fields of planned languages, interlinguistics, and language planning: events, new publications, conference reports, and more. The journal is available for free online in both Esperanto and English.
