A few years ago the brochure "Die Welt des Ansichtskartensammelns" (The World of Colleting Picture Postcards), Volume 7 of the series "Ratgeber für Briefmarkensammler" / "Stamp Collector's Guides", had been published and still is very popular. However, it only contains a small list of literature concerning the subject. That is why Thomas Fürst, one of the authors decided to work on a much more extended list of literature about picture postcards. And here it is. Apart from that this bochure contains an overview of the history of deltiology.
