Histat serves as access-platform of time series data collected in the framework of economic and social historical research.All together, all in the database Histat contained time series enclose about five and a half million values. From the year 1800 at least thousand values for nearly each year are available, from the middle of the 19th century there are already more than 10.000 values on hand via Histat, and with the foundation of the German Empire (in 1871) there are more than 20.000 values available per year. The highlights are the years at the beginning of the 20th Century: for several years there are about 60.000 values available via histat.

MIA contains the writings of 592 authors representing a complete spectrum of political, philosophical, and scientific thought, generally spanning the past 200 years. Being a communist means working for the self-emancipation of the working class; it means striving to unite the working class, in all its diversity, in the struggle to overthrow capitalism. In the 1840s, Marx and Engels placed communism on a scientific footing through the theory of dialectical materialism. Marxists are those who have continued this ever since. If any one of the following criteria apply, the MIA Collective may decide to place the writer into the Reference Archive: (i) they pre-date Marx and Engels, (ii) they specifically reject Marxism, (iii) their work is practically and theoretically unconnected or hostile toward the workers movement, (iv) their work is idealistic or lacking in dialectic. Where a writer contributes to Marxist theory and practice for a part of their life, while other works lie outside of Marxism, then the whole of their writing will be placed in the Marxist Writers' Archive.Contains: Karl Marx/ Friedrich Engels - Werke ; Rosa Luxenburg; August Bebel; Antonio Gramsci ...
