Subject:  Collection Analysis and Published Dates as a Percentage of the 
Collection

Hello All -

I am new to this list - so please accept my apologies if my question or 
search for information has been addressed in previous posts.

I am working on a collection analysis project where one goal will be to 
determine what percentage of my collection has been published within the 
last 5 years and the last 10 years.  Does anyone know where I can find 
industry standards or benchmarks which will tell me what a good (or bad) 
percentage is?  For example if 10% of my collection has been published 
within the last five years - would this be a good percentage - 
representing adequate currency of information?  The size of collection 
we are looking to analyze is around 75,000 items.  This is a technical 
library collection that supports research and development for a variety 
of engineering and science disciplines; the bulk of working involving 
mathematics, electronics & electrical engineering, physics, chemistry, 
mechanical engineering and the material sciences.

Any help, feedback and/or guidance is greatly appreciated.

Please respond directly to me at dwguy_at_sandia.gov

Best Regards,

Donald W. Guy
