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

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.
