You can continue to generate and print courier slips through this web site. But stay tuned, we’re building a new courier slip creation system to make it easier than ever to create slips.

If you’d like to report a service issue, please visit our “Contact Library Courier” page and select the relevant form.

Libraries are strongly advised to read and understand Colorado ILL Best Practices and the Interlibrary Loan Code for the United States, both of which provide the basis for library resource sharing in Colorado.

Costs

With courier costs, each library situation is unique and is dependent on local interlibrary loan practices. Operating costs are calculated annually on behalf of all participating libraries, and are a direct result of the previous year’s resource-sharing activity (July through June).

CLiC has two goals:

  1. Continue to encourage resource sharing throughout Colorado and to maintain affordable pricing for libraries that voluntarily request to participate in the Courier service.
  2. Ensure sustainability of the statewide Courier service by maintaining predictability in libraries’ costs while still allowing CLiC to “pay the bills” associated with operation of this statewide service, which has handled more than 2.6 million physical items EACH of the past two years [2018 & 2019].
