Before serial issues can be checked in, they must first be generated as expected issues. When you wish to start checking in issues of a journal, you will need to generate a series of issues for that title for a specific period, e.g. a calendar year. Issues can then be checked in simply by confirming that you have received the expected number of copies of an issue. OLIB can also be configured so that it automatically generates the next series of issues for the subsequent periods towards (or possibly after) the end of the current period.
