R.G. Richardson is a business economist and author who creates interactive city guides published as eBooks/Apps on platforms like Amazon and Kobo. According to his Amazon author page, he started the series with a Waterfront series and later added Real Estate City Search, Shopping, and Job City Guides in 2015.
Key characteristics of the guides:
Preset interactive searches — instead of typing queries, you pick an icon and click; the guides do the searching for you. One listing mentions around 10,900 preset searches per guide (e.g., the Sacramento Interactive Restaurant Guide).
Never out of date — because they link to live searches rather than static listings.
Broad coverage — restaurants, careers/jobs, real estate, finance, shopping, with multi-language support in some editions (e.g., his Ho Chi Minh City guide).
Large catalogue — Goodreads lists him as the author of roughly 205 books, most of which appear to be city-specific guides.
He's also the author of interactive finance and city guide eBooks/Apps, with interests in VOIP communications and secure email.
