Fall 2011 OLIS-LORI Delivery Items Count Results

About the Survey

LORI libraries statewide participated in the now biannual Delivery Items Count in November 2011. 192 library facilities that receive regular OLIS-LORI Delivery services recorded and reported their out-going item counts. The survey took place from November 13 through November 19, 2011, with 99% (191) of network libraries participating. All together, 53,435 items were transported in the OLIS-LORI Delivery system during the week.

Survey results provide OLIS with valuable insight into the growth of Rhode Island’s resource sharing activities. The information is crucial for OLIS to plan for the future of this vital service to the state’s libraries.  

Survey summaries 

The volume in Delivery has grown steadily over the years.  The increase was apparent in the data OLIS collected from the items count surveys from 2001 through 2010.  The March 2011 items count marked the first decline by 270 items in the week’s total. Since the number was statistically insignificant, and the items count took place in a different time of year, it is pre-mature to draw any conclusion from the drop.
The total count from the November 2011 survey presented a surprising 4.94% decrease from the survey held in March 2011 and 5.44% decrease from November 2010.  It is safe to conclude that number of items transported in 2011 was lower than in 2010 based on the data collected from the delivery items count surveys.

The following are comparisons drawn from this and the past surveys:

  • In a typical week of OLIS-LORI Delivery, a total of
    • 53,435 items were transported in November 2011
    • 56,074 items were transported in March 2011
    • 56,344 items were transported in November 2010
    • 49,815 items were transported in October 2009
    • 47,073 items were transported in October 2008
    • 40,038 items were transported in October 2007
    • 36,274 items were transported in October 2006
    • 25,693 items were transported in October 2001

The change in the number of participating libraries is attributed to school closings and library reductions in staff and/or services.
