    3/13

    Best when combined

    - Loans of books are down from 60 000 to 40000

    - Full-text downloads are up from 40 000 to 60000

    - BUT student numbers have halved!

    - NO! student numbers have doubled!

    HOW?????????????

    Technical University of Atlantis

    A brand new institution, the collection of

    monographs has to be built up. An initial fundof A$1,000,000 has been given, and now thelibrary has been asked to explain to theSenate Library Committee how they are

    going to divide this equitably amongst thedifferent departments

    Per head division

    Add up all students, dividemoney by total and

    multiply result pernumbers in eachdepartment!!!

    Problem!

    The Faculty Librarian for Applied Sciences

    looks at this and says Theres no way wecan have A$230,000 for Marine Biology, butonly A$10000 for Vulcanologyyou cantbuild a collection with only A$ 10000!!

    Solution

    Divide the budgetinto two:

    Use half for anequal distributionfor departments,and half per

    student

    Per dept Per student Total

    Everyone happy!

    The Faculty Librarian for Engineering clears his

    throat: Thislooks

    fair, but we have been toldthat as a library we need to support researchand we all know that my Faculty producesmost of the research! AND we know that the

    material used by researchers and studentsdoing research is more expensive! But thisdoesnt show it!

    Solution

    Divide the budget into three:

    Use one-third for an equal distribution fordepartments, one-third per student, and onethird to be divided on the basis of researchoutput and postgraduate students

    Now everyones happy!

    Head of Technical Services is still frowning:

    Weve taken into account the number ofstudents, research needs and even protectedsmaller departments, but in my departmentwe know that the price of material varies

    widelyVulcanology pays four times asmuch as Horticulture for their material! Surelythis must be taken into account?

    Final solution?

    Divide into quarters:

    One quarter per departmentOne quarter for students

    One quarter for research

    One quarter for cost of items.
