Conferences are usually organized either by a scientific society or by a group of researchers with a common interest. Larger meetings may be handled on behalf of the scientific society by a Professional Conference Organiser or PCO.
The meeting is announced by way of a Call For Papers (CFP) or a Call For Abstracts, which is sent to prospective presenters and explains how to submit their abstracts or papers. It describes the broad theme and lists the meeting’s topics and formalities such as what kind of abstract (summary) or paper has to be submitted, to whom, and by what deadline. A CFP is usually distributed using a mailing list or on specialized online services. Contributions are usually submitted using an online abstract or paper management service.
