Statewide Library Delivery Service

In an effort to get a more accurate estimate of the number of items delivered, CSL asked libraries to count their incoming and outgoing items daily and report those numbers quarterly. By the last quarter of FY2019, 135 libraries submitted data (63% of libraries that receive delivery). Extrapolating to all 215 libraries and rounding off the numbers, the service delivered 1.5 million items in FY 2019 (1,486,021 items incoming and 1,475,181 items outgoing).

The chart below shows the monthly estimates of incoming volume for both FY2018 and FY 2019.

The Excel file below contains spreadsheets with data for FY2019 for each of the following:

In an effort to get a more accurate estimate of the number of items delivered, CSL asked libraries to count their incoming and outgoing items daily and report those numbers quarterly. By the last quarter of FY2018, 139 libraries submitted data (64% of libraries that receive delivery). Extrapolating to all 216 libraries, **the service delivered 1.5 million items in FY 2018 **(1,498,405 items incoming and 1,519,676 items outgoing).

The chart below shows the monthly estimates of incoming volume for FY2018.

Periodically the Connecticut State Library asks libraries receiving deliverIT CT (formerly Connecticar or Ccar) service to count items they have receive during a sample week. The results of these surveys are being used to keep track of trends and to improve delivery service. The results of previous volume surveys appear below.

The Connecticut State Library extends a * thank you* to all library staff members who took the time to count and report their statistics.
