- The Burgundy Effect in Off-Line Union Catalogs of Serials. De Groote, Stefan And Others Interlibrary Loans Library Materials Models Serials Tables (Data) Union Catalogs Discusses interlibrary lending (ILL) systems and explains the localization effect--called "the burgundy effect"--which results in a partial union catalog of serials locating a higher percentage of ILL requests than an up-to-date catalog over a number of years. An econometric model, the Weibull distribution, is used to calculate localization indices. (20 references) (LRW)
