These are general rules.
APA Publication Manual Section 9.51 [Excerpted]
Most APA Style guidelines are applicable to annotated bibliographies. In general, it is not necessary to cite the work being annotated in the annotation because the origin of the information is clear through context. However, do include in-text citations if you refer to multiple works within an annotation to clarify the source.
Instructors generally set all other requirements for annotated bibliographies. In the absence of other guidance, format an annotated bibliography as follows:
From CMOS 14.64 and figure 14.10.
MLA Handbook 5.132
Style a source in an annotated bibliography just as you would one in a list of works cited, and then append an annotation to the end of the entry, in-dented an inch from the start of the entry (to distinguish it from the half-inch hanging indent of entries composed of more than one line).
Annotations describe or evaluate sources or do both. They should not rehash minor details, cite evidence, quote the author, or recount steps in an argument. Annotations are generally written as succinct phrases.
Moore, Nicole. The Censor’s Library: Uncovering the Lost History of Australia’s Banned Books. U of Queensland P, 2012.
Comprehensive history of Australian print censorship, with discussion of this history’s implications for questions of transnationalism and the construction of the reader.
But annotations can also be given as complete sentences.

The book provides a comprehensive history of Australian print censorship and discusses its implications for questions of transnationalism and the construction of the reader.
In an annotated bibliography, the annotations should generally be no more than one paragraph. If, however, you need several paragraphs, indent each one but do not add an extra space between paragraphs. Follow your instructor’s guidelines on the use of phrases or full sentences and the length of annotations.
The list should be titled Annotated Bibliography or Annotated List of Works Cited. Writers may organize the bibliography alphabetically by author or title (as for a normal list of works cited), by date of publication, or by subject.
