8.5.1. First issue lacks numbering
When the first issue has no numbering (including a publishing date or a copyright date that could be used to supply a chronological designation), supply a designation following the form of numbering on subsequent issues when that is known, per AACR2 12.3D1. Example
When only a single issue is in hand, give "[No. 1]-" or its equivalent, according to AACR2 12.3D1. First, be sure, however, that the publication is really a serial by examining the contents and any stated intent to publish further issues. Example
When a serial is more likely to be identified by date and the date of coverage or publishing can be determined from the piece (e.g., the preface) or other sources, supply a chronological designation rather than [No. 1]-. Example
