• Questions are welcome at any time, but we may defer 
answering a question until later in the session 
• Interactive discussions are welcome
•In 1997 the Arkansas State University library had no 
equitable means of making allocations 
•Funds had not been reallocated/redistributed in many 
years 
•One department accounted for nearly 20% of all 
collection development expenditures 
•There was no funding to support new programs
•We searched literature to discover methods of making 
allocations, including the use of a formula 
•We chose to use a formula based on one used by Colorado 
State University and described in SPEC Kit #36
Do these steps before selecting formula 
factors
•Doing this is much like a brainstorming session 
• Cost of materials 
• Degrees awarded per department or program 
• Faculty per department or program 
• Number of course sections offered 
• Number of courses in catalog 
• Number of degree programs 
• Number of majors in each program 
• Semester credit hour production (actual enrollment) 
• Use of materials
•Evaluate and refine the list 
• Eliminate duplicates and non-viable suggestions 
• Identify the factors that are most relevant to your campus
•What we used 
• Cost of materials (from the Library and Book Trade 
Almanac) 
• Degrees awarded per department or program 
• Faculty per department or program (FTE faculty) 
• Number of course sections offered 
• Number of courses in catalog 
• Number of degree programs 
• Number of majors in each program 
• Semester credit hour production (actual enrollment) 
• Use of materials
•Determine what data is available or could be gathered 
• Both internal (within your library and within the field) and 
external (campus, community, company, etc.) 
• Eliminate possible factors for which data cannot be obtained 
•Gather samples of available data
•The original factors we used 
• Semester credit hour production (actual enrollment) 
• Number of classes offered 
• Degrees awarded 
• Faculty per department 
• Cost of materials from Library and Book Trade Almanac 
•Other factors that could have been used 
• Number of degree programs 
• Departmental external funding and/or research 
productivity 
• Use of materials 
• Number of courses in catalog
•Weights 
• Weighting is the assigning of values to indicate the 
importance or impact of each factor in the formula relative 
to the other formula factors 
• The assigned weight values are inserted into the Excel 
spreadsheet and are used in formula calculations
•Assigning weights to each factor 
• These should be based upon each institution’s priorities 
and culture 
• Library Committee 
• Faculty Senate 
• Institutional Administration 
• Something else? 
• We subdivided some factors before assigning weights 
• Do test runs and adjust weights if needed
How the Formula Works 
(by non-mathematicians)
Screen Shot of a Previous Formula Run
•You can do separate formula runs for… 
• Books 
• Journals 
• Print 
• Online resources (databases/ejournals/eBooks) 
• Any other budgets your library may have 
• Or any combination of these 
•We chose to run a single formula for all allocations
•Before running the formula, determine how much of your 
budget to allocate and how much to keep back for library use 
(if any) 
•You may want or need to make adjustments to individual 
allocations after running the formula 
• Do no harm 
• Nonparticipation 
• Special entities or protected programs
•Your formula will probably need to be modified at some 
point in the future 
•We have changed our formula 
• Weights were adjusted 
• Added departmental external funding as a factor in 2012
•Document, document, document! 
•Make the decisions and modify the formula to fit your 
library’s needs 
•Feel free to contact either of us with any questions you 
may think of later
