The Church of Spiritual Technology, also known as CST, is a Californian 501(c)(3) non-profit corporation, incorporated in 1982, which owns all the copyrights of the estate of L. Ron Hubbard. The CST is doing business as L. Ron Hubbard Library. The organization receives its income from royalty fees paid to it by licensing of the copyrighted materials of Dianetics and Scientology to Scientology-connected organizations approved by the Religious Technology Center, and from its wholly owned for-profit subsidiary Author Services Inc. which publishes and promotes Hubbard's fiction works.

In a 1993 memorandum by the Church of Scientology International, the role and function of CST has been described as follows:

"[...] CST [...] is an autonomous church of the Scientology religion outside of the international Scientology ecclesiastical hierarchy. CST conducts an extensive program of activities to preserve and archive the Scientology Scriptures for use by future generations. CST also owns the option to acquire RTC's rights to the Scientology advance[d] technology and religious marks under three narrowly defined sets of circumstances, each of which contemplates a serious threat to continued existence of the religion. CST is the principal beneficiary of Mr. Hubbard's estate, provided that it obtains recognition of its tax-exempt status.
