The present study determines the co-authorship factor in the Iranian scientific output between 2000 and 2006 as reflected in the science, social science art and humanities citation indexes made available through the Web of Science database. Webometric indicators were used. The data were extracted in plain text from WOS, analyzed using HistCite software and counted in MS Office Excel program. Of the Total of 25320 documents indexed, 24480 documents were in Science Citation Index, 783 in Social Citation Index and 57 in Art and Humanities index. The findings indicated that co-authorship factor in the period studied had been on the rise. The highest participation rate belonged to the documents with two or three authors. General coauthorship factor was 0.59. The year 2006 had the highest coauthorship factor (0.62) while the year 2000 had the least (0.55). Bradford and Lotka laws were applied to the data sets. The Lotka’s Law only held true for the science citation index. The Bradford’s Law, however, held true for all indexes. In all citation indexes, the United States with 1865 documents (7.38) had the highest degree of coauthorship in Iranian scientific output.
