Alongside the International Conferences on Magnetic Fluids we have now three bibliographies compiled in 1980, 1983 and 1987. A lack of space restricts us here to publishing a bibliography or papers only from the years (1986-1988). Omitted are publications prior to 1986 not presented in the previous three bibliographies (about 1500 entries). All the available data on patents are here (not presented in previous three bibliographies) without the restrictions over the publication years.
