Feasting on the Word is classified as a Bible Commentary. The ILCW series which has a similar structure is classified as a monograph.
Other lectionary based commentary resources that are labeled monographs in apparent error are:
Preaching and Worshiping in Advent Christmas and Epiphany
Lent for Everyone (2 volumes)
Preaching from the Lectionary
This mixture means that they cannot all be included in a Commentary collection section in the various Guides.
