The PBS maintains a "massive" online encyclopedia about bulbs with "an absolute wealth of images and information" stored in a
Wiki that is accessible to the general public. Other topics covered in the wiki include
cultivation tips, information on bulb-growing
climates, sources for geophytes, a
bibliography of books about geophytes, and a section on "legacy" bulbs that outlast their original homes. The society also runs an active
online e-mail discussion group, "The PBS List," that is open to anyone, whether or not they are a PBS member. People can join the list to ask questions or share information about bulbs. Paid members of the society receive a quarterly print publication, and can participate in
exchanges of seeds and
dormant bulbs several times a month. The exchanges sometimes include rare and unusual species. == References ==
