The literature database ISL-SEABASE represents an important knowledge source for industry and commerce, research and education. The database increases each year by about 4,000 bibliographic records.

All new entries of the ISL library are bibliographical recorded and made available as regards content (descriptors, abstracts). Besides reference books also studies of the market, reports of an inquiry, transactions, economy statistics as well as business and annual reports become particularly incorporated. Contributions from about 230 national and international professional journals are evaluated selectively after relevance. The literature evaluation and enquiry is based on the thesaurus developed in the ISL "Seeverkehrswirtschaft und Logistik" (only in German language). Digital documents increasingly are included as a full text under consideration of the copyright.
