p.286. Inserting an image "...into an LibreOffice document". Should be "a", not "an". Obviously a through edit from the OOo original! And "or from other programs" would be better than "and".
p.291. "(described on the next page)". Better "described below" as the description starts on the same page.
p.293. The toolbar has *two* callout symbols. The first seems to be Writer-specific; second one belongs to Draw. Should this be explained? It looks odd otherwise
p.295. Fig 286 should be Fig 290. Fig 291 should be Fig 292.
