The Conjuring Arts Resource Center on Manhattan has a 12,000-volume library of books about performance magic, including some rare items dating back to the Fifteenth Century:
The library also maintains an extensive collection of manuscripts of magic methods, some dating back to the 15th century. Included in this collection is a rare, unpublished manuscript by Marion Spielmann, the only known student of the great card master Charlier. Conjuring Arts also has an interesting collection of letters including correspondence between Hugard, Braue and Fleming, as well as a great selection of Ed Marlo letters.
For those interested in the recorded dialogues of the magic community, the library has a magic periodical collection, some published as far back as the 18th century. Complete collections of The Sphinx, Genii, MUM and other major and minor periodicals are also available.
