OPLIN (Ohio Public Library Information Network) provides Internet services to the public library systems of Ohio. For the most part, we provide one broadband connection to the main library of each system, and access to the commodity Internet for any public library which routes Internet-bound traffic through our network core in Columbus, Ohio. While OPLIN also provides some other services to libraries, none of them are possible without our dependable, robust, broadband network connections.

One of the unusual characteristics of OPLIN is the fact that it provides and manages this physical network connecting libraries to the Internet; most other library “information networks” primarily deliver content and services over a physical network provided by some other organization. When OPLIN was established in 1995-96, the network was built from copper-wire ‘T1’ circuits. In 2006, fiber-optic ‘Ethernet’ circuits began replacing the older T1 circuits.

Service objectives:

  • Incident Response: OPLIN staff will respond within one hour to malfunctions of Internet connections during regular business hours Monday through Friday from 8:00 a.m. to 5:00 p.m., excluding State of Ohio holidays; contact us through the OPLIN Support site. After-hours support is provided 24/7/365 through the Ohio Office of Information Technology (OIT): AFTER HOURS NUMBER FOR NETWORK OUTAGES ONLY, 614-644-6860.
  • Incident Resolution: OPLIN staff and/or OIT staff will open an incident ticket with the telecommunications vendor(s) and will work collaboratively toward resolving the incident within 4 hours.


How does OPLIN decide how much bandwidth my library will get?

We try to buy circuits big enough so every OPLIN participant has an Internet connection that is large enough to insure that the participant's average circuit utilization does not exceed 70% during peak hours.

Does our library have to go through OPLIN for network services?

No. Libraries can purchase network services from any vendor. However, since OPLIN offers a free connection between each library system and the Internet, OPLIN network service is almost always the best deal.

Does my library have to go through OPLIN to get network connections for branches?

No. We recommend you first contact your local telephone company and any nearby cable or wireless providers for their circuit rates. We also offer the option to go through our state contracts (at discounted rates) for library branch connection circuits. Each library must decide the best compromise of quality, price, and performance to meet their needs. The OPLIN Support Center will be happy to review any plans provided by local vendors and give advice.

Does OPLIN provide any help with network planning?

To help you keep up with the network demands of your libraries, OPLIN staff can prepare bandwidth usage reports and a review of options available through the State of Ohio. Contact the OPLIN Support Center for more information.

How far in advance do I need to contact the OPLIN Support Center if my library needs to get a new circuit or move an existing circuit?

We recommend that you contact the OPLIN Support Center for information and costs prior to placing any circuit request, and we also recommend that you place your circuit request at least ninety (90) days before your library needs to have the circuit installed or removed.
