This tag denotes that the tagged video is multisource. The tagged video should feature more than one source, and those sources should have no prior history of being used in tandem. Some guidelines for usage are as follows:

• If the sources used fit a noticeable theme, then the themed multisource tag should also be added. Additionally, if the theme fits the criteria for one of the several "all-star" tags, it should be added as well.
• Videos that only use a source that is comprised of a series of smaller sources, such as a works using Gachimuchi Pants Wrestling or the Super Mario Series, should not receive this tag.
• Videos that have a bait and switch element should not receive the tag, unless either the pre or post switch sections are multisource.
• Videos only using sources with a history of being used together such as Cookie☆ and Inmu or nico nico's three major religions should not receive this tag.

It is important to note that tagging sources is not a replacement for the multisource tag, and vice versa. Any video that fits the criteria to receive this tag should be given it regardless of if the work has it's sources tagged or not.
