I have been in the process of writing reviews for books that I have read. They are by no means complete, but are intended to summarize of the principles (or plot) of the books in case I forget (note that for fiction this constitutes a spoiler). The complete book is reviewed, principles explained, and, for fiction, the entire plot is summarized. At the end of the review are various tidbits have been collected either on writing style or specific principles that could not be included in the review.
