Stjepan Kugli and Albert Deutsch appeared independantly on the Zagreb publishing scene in 1881 when they bought Lavoslav Hartman's bookstore in which they had until then been employed as Hartman's assistants. By continuing Hartman's business under the name The Lavoslav Hartman Library (Kugli and Deutsch), Stjepan Kugli and Albert Deutsch maintained the tradition stemming from Gaj's croatian national revival ideals. Deutsch withdrew from the company in 1902 due to illness and since then the name of the the company was changed several times (in order to emphasize the tradition of publishing that it was continuing), but at the root it was always L. Hartman (St. Kugli) and starting from 1915 (when Kugli passed away) St. Kugli. From 1881 to 1945 Kugli and Deutsch were the largest publishers of children's books, especially picture books, which rarely had the names of the illustrators and year of publishment printed on them. Since many of Kugli's publications don't have the year of publishment printed on them, the problem of determining the books' date of publishment is being solved by means of the firms and the addresses on which they operated, as well as the artistic design, which aids in the rough dating of the books. The bookstore and stationery store of Stjepan Kugli was, from 1902 until his death in 1915 (and even after that, up until 1945), the largest and most complete in Zagreb. Stjepan Kugli used every available opportunity to advertise the books and magazines he published or sold and he showed himself to be not only a good publisher that payed attention to the market, but also a good salesman. Due to the need for information, but also availability at a low price, the popularity of periodic publication had grown during the 19th century. From 1888 to 1923 Kugli and Deutsch (and afterwards Kugli's sons) had been publishing Dom i sviet, a biweekly illustrated magazine printed in large format that Kugli had launched, modeled on similar publications in western and middle Europe. Other than interesting facts from his homeland and the world, he also advertized books and magazines they published or that were able to be purchased in Kugli's bookstore.
