::Seems a good idea, as it has "grown like Topsy". A residual summary is definitely necessary, as one of the main things about Norwich is its history. Readers with a general interest should be provided with enough historical background, and, if they wish to know more, then off to the separate History entry. The one thing I do have some reservations over is the 20th Century section, and the latter part of the Victorian. These contain information (such as shawls, brewing etc.) which is of an "industrial" nature; rather more so than truly "history". I would suggest that these pieces of information remain in the main article in pretty much their present form. It may of course be necessary to coalesce them under a heading of (for example), "Norwich Industries" or something of that nature.
