The number of papers refers to the number of years of publications accumulated year by year from the year of publication. Periodicals have a volume number and an issue number, and the volume number should be above the issue number. Simply put, the volume contains a wider time range, and the issue number is a specific part of the publication, which can be easily understood.
Periodicals are classified by content and divided into volumes and issues by time. A volume is a time classification on it. The "number of periods" here is the number of periods issued in chronological order in 1 year; The "volume" is the chronological number of this publication, which has been accumulated year by year since the year of its publication.
For example, 198 1 started the Journal of Sun Yat-sen University series, and in February 2004, Volume 24, Issue 6, which means that the Journal of Sun Yat-sen University series is bimonthly, so issue 5438+02 was published in June. And this "24" is the volume number. 198 1 all papers in Journal of Sun Yat-sen University were the first volume, and all six papers in Journal of Sun Yat-sen University in 2004 were the twenty-fourth volume in turn.

In order to sort the periodicals for easy query, domestic periodicals are divided into volumes and issues according to time. Volume is the time classification above the cycle, volume is the number sorted by year since publication, and cycle is the number sorted by time this year.
For example, the papers published in March 2065438+2007 may be, according to the volume number and issue number, 23 volumes and 3 issues. The regulations on the volume number and issue number of periodicals in China are relatively uniform and easy to identify.
There is no uniform standard for the volume number and issue number of English periodicals. Generally speaking, foreign periodicals don't just take the year as the volume number. They can publish one book, several books or several books a year.
Therefore, English periodicals often only set volume numbers, not issue numbers. For example, an English periodical publishes a volume every half month, which is similar to that of China, so there is no issue number, and only the volume number is used to distinguish it.
