In the U.S. it is the Library of Congress. In Canada contact ISSN Canada at the National Library of Canada. If there is a title change, a new ISSN must be assigned. Title changes should be considered most carefully. Any necessary change of title should be made with the first issue of a new volume.
Telephone number is optional.
Volume number, issue number, and date should appear on the cover and title page of each issue. Continuous pagination should be used for issues within each volume of the periodical, rather than beginning numbering anew with each issue. Only Arabic numerals should be used. Staples should be used only in the inner margin, never through the text. Heavy-duty staples should not be used to seal the contents for mailing purposes.
