A press release from Bud Webster, SFWA Estates Liaison:
With some significantly hard work, Michael Capobianco has created the SFWA Estates Page at www.sfwa.org/estates-contact-information.
If you know of an editor or publisher who wants to reprint material by a deceased writer but has no idea how to seek permissions, send them there.
Eventually, the Agency names will be linked to their websites, with full contact information. In the meantime, if you need more help, contact me at estates [at] sfwa [dot] org.
