What part of an annotated bibliography helps the researcher remember the source's content?

The summary in the annotation plays a crucial role in helping the researcher recall the content of a source. An annotation typically includes a brief overview of the main ideas or arguments presented in the source, allowing the researcher to quickly grasp the essence of the work without having to revisit the entire text. This is particularly useful when compiling multiple sources, as it provides a snapshot of the information contained within each one. By summarizing the key points, researchers can efficiently evaluate the relevance of the source to their topic and make informed decisions about its inclusion in their work.

The other elements, such as the title of the source, bibliographic citation, and publication date, serve important purposes in terms of identification and reference, but they do not provide the substantive content summary that an annotated bibliography seeks to convey.
