• MAPS' MDMA Literature Review with PDF copies of most papers, updated monthly.
  
• Albert Hofmann Foundation's comprehensive bibliography on LSD and Psilocybin, 1943-1983 (over 4200 entries), originally gathered by Dr. Albert Hofmann for his personal use. The Albert Hofmann Foundation has granted permission to have these documents scanned into PDF format and made available on the Internet.
  
• Torsten Passie's Psychedelic / Psycholytic Therapy Bibliography, a complete list of all studies of the therapeutic use of psychedelics from 1931-1995, preface by Dr. Leuner and introduction by Dr. Passie.
  
• Alexander Shulgin's annotated and categorized MDMA bibliography (up to 1992).

  Note: Alexander Shulgin's annotated and categorized MDMA bibliography (up to 1992) is searchable only through the expert interface. This avoids possible confusion in the simple interface from two entries for some of the same references, with those in MAPS' MDMA literature review presenting the original abstract and PDF and those in Alexander Shulgin's bibliography presenting his summary in place of the original abstract. All other references can be accessed through either the simple or the expert interface.

MAPS has also scanned the entire collection of the issues of The Psychedelic Review, the journal started by the Harvard psychedelic research team of Ralph Metzner, Richard Alpert and Timothy Leary. Issue #1 was first published in June 1963 and the final issue, #11, was Winter 1970/1971.
