The effect of DOCLINE on interlibrary loan volume and patterns among health sciences libraries in Michigan: preliminary analysis.

Six years of statistics on interlibrary lending and borrowing among basic unit health sciences libraries in Michigan are examined to determine the effect of the availability of an automated interlibrary loan system, DOCLINE, on interlibrary lending volume and patterns within Michigan. A trend analysis projection of expected volume is made and the predicted value compared with the actual value following the adoption of the DOCLINE system. Interlibrary loan (ILL) volume is tested to see if yearly volume increases are statistically significant. The number of libraries changing from net lender to net borrower or the reverse after the adoption of DOCLINE is tracked. Results fail to support the expectation that DOCLINE would produce major change in ILL volume or pattern.
