Consolidation Skews Field In Magazine Distribution
Joel R Anderson's company, Anderson News of Florence, Ala, has risen to become nation's largest magazine wholesaler, delivering 4 of every 10 magazines on retail racks nn United States; Anderson is symbol of swift consolidation that has left battlefield littered with defunct wholesalers, large and small; consolidation has drawn attention of Justice Dept's antitrust division and has created mounting, intense consternation among publishers, who say they find it more difficult and expensive to get their publications distributed; some even blame wholesalers for deaths of Details, Mirabella and Life magazines; Anderson claims he is being squeezed by large retailers to offer more service and better prices, reducing his gross profit on each copy sold; he also feels that too many magazines are being published for dwindling retail racks available; photos (M)
