We can omit certain types of non-textual
content that aren't suited for an audiobook, like number-heavy tables, but we can't include our own paraphrase or comments in the recording. That shouldn't be controversial; it's a basic Librivox principle, found at the top of our recording policy page
. ("You may not add or remove text. You may not add an audio introduction or editorial comment. You can however include this kind of thing in the catalog text.") One option is to skip the table and mention it in the book summary with a page number, so that the listeners are aware of it and can consult the text if they're interested. Another option is to read the table, which is somewhat difficult to do in this case, since it conveys both the proportions across the columns and the trend across the rows. You could read it row by row, giving the column titles in full for the first row and abbreviating them for the following rows, as in:
total number tried: 2730,
charged with military offenses: 1688,
offenses against the state: 66,
charged under rubric 4: 53,
This is pushing the limits of what can be considered reading out loud, but not exceeding them, since you would be preserving the original information in the table and not adding anything of your own.
When footnotes apply, I have ended the topic by announcing, "Footnote regarding _ ...<footnote text>... End of footnote."
This is acceptable, though unusual for LV. We normally place footnotes at the end of the phrase or sentence or paragraph and start them simply by saying "footnote". You as soloist/BC can also decide to skip footnotes altogether, since they aren't part of the main body of text.
