Description: this is the name that will appear in the drop-down menu when creating a new serial subscription; make sure it is descriptive

Unit: this is the unit used for counting the cycle of publication. Choose either none (for irregular frequencies), day, week, month, or year.

Issues per unit: this is how many issues are published during the unit chosen above (this will usually be 1).

Units per issue: this is how many units must we count until the next issue is published.

Display order: this is the display order in the drop-down menu when creating a new subscription (you may want to put the most used frequencies at the top and the less frequent at the bottom; the top-most position is 0). Several frequencies can have the same display order value. If this is the case, they will appear in the order they were created.

Tip

To understand ‘issues per unit’ versus ‘units per issue’ you can read it as ‘<issues per unit> issue(s) every <units per issues> <unit>’. For example, a biweekly frequency (every two weeks) would be ‘1 issue every 2 weeks’. So ‘issues per unit’ would be 1 and ‘units per issue’ would be 2. See below for more examples.
