Don’t get “crop happy” and cut away too much of a document. There may be clues in the edges that may not be immediately relevant. The illustration has obvious clues in the license plate and the home. Neighbors in the census may be relatives, cutting them out of the image you save may cause to miss that clue years later. Handwritten records where just the “entry of interest” is saved can be hard to analyze without the context of other records to serve as a guide.
