National Library Statistics

Annual statistics on U.S. public libraries are available from the National Center for Education Statistics. Data is collected by state library agencies and compiled by NCES with the support of the U.S. Census Bureau’s Division of Governments and the U.S. National Commission on Libraries and Information Science (NCLIS). The annual NCES report on U.S. public libraries provides data for the nation, each of the 50 states and the District of Columbia, and each of 11 population ranges. Major data categories include: library name and address, outlets, staffing, income and expenditures, collections, Internet computers, library visits, circulation, reference questions, interlibrary loan and use of electronic services.

Frequently Asked Questions:

What is “Who’s On My Wifi” Library Edition?

Who’s On My Wifi Library Edition is a product which monitors and counts the number of devices on a wireless network and provides libraries with easy to read and/or understand statistical counts. One of the unique features of the service is the ability to anonymize the device information of visitors to the network, while still providing high quality statistics. This feature allows the libraries to offer privacy of all patron data used for reporting. Another unique feature this product offers is the ability to calculate total session counts while excluding specific devices, such as library-owned devices, in order to meet specific requirements. This allows the client the ability to customize the data being used for reporting.

Is my library required to use Who’s On My Wifi to report my data for the state report?

No, your library is not required to use this product. Your library may use a different wireless reporting system such as Cisco Meraki or another product.  Who’s On My Wifi Library Edition is provided at no cost to your library.  However, as in years past, your library is required to fill out the State Statistical report, which has a question about wireless use.

How can I install the Who’s On My Wifi software at my library?

Detailed instructions and a webinar are coming soon.

Once installed, what type of support should I expect from Who’s On My Wifi?

Who’s On My Wifi will check in 30 days after installation to make sure the process is going smoothly. In addition, you may call 800-278-5099  if you are experiencing issues.

Will Who’s On My Wifi interfere with any of my other network equipment?

OPLIN has reviewed this software and does not believe it will interfere with any network functions. The agent runs passively in the background. It does not perform any network functions aside from gathering Wifi usage. The agent can be installed on a Mac or PC and can run in the background; however, the device where the agent is running should be left on to gather usage information anytime your Wifi network is in use.

It can be installed on a Windows server. There will soon a Meraki plugin. The service is compatible with Meraki today, but there is a network change that is required. The plugin would eliminate the need for a network change.

Should I use Who’s On My Wifi on the library’s bookmobile or other outreach efforts?

Yes. If your library uses wireless on a bookmobile or in other outreach efforts, those numbers should be reported in the State Report. Thus, you should use Who’s on my Wifi or another product to count wireless use.

How tech savvy do I need to be to install and manage the Who’s On My Wifi service?

For the majority of networks you can install and run the service with very basic tech knowledge.

What should the IT department know for large library networks?  

There is no active listener on the network with the Who’s On My Wifi solution.  By just using a simple ARP scan to gather device inventory there is no concern about general traffic listening, needing to configure a SPAN port, or only working on managed switches or vendor specific hardware.

The solution is easy to connect because all traffic goes over outbound HTTPS which is just port 443. It is universally open on all firewalls, there is no inbound port requirement, and it only requires about 500kb per day in internet traffic, which is less than a single image per day.

You can specify the VLANs that you would like to monitor without having to set them all up.

Finally, it works on your existing infrastructure.  You do not have to replace your current routers or access points.

My library has a separate wireless network for staff. Should my library count use on this staff-only network?

Yes. The count you report to the state should be of all unique client sessions per 24 hours including staff and library-owned devices.  Unique clients are determined by MAC address.

Should we count all sessions or only human-initiated connections?

We have received further guidance from the federal government that all sessions should be counted. This statistic should reflect all use of the wireless network.

How should my library report the sessions?

On your State Annual Report, you will report number of sessions per day (24 hours) with a reconnect tolerance of one hour. This means if a device is seen in morning and not seen for over an hour and reconnects in the evening it is reported as two sessions. This is the default setting for Who’s On My Wifi Library Edition.

What is a MAC address?

A MAC address, or media access control address, is a unique identifier assigned to network interfaces for communications on the physical network segment.  Each device connected to the wireless or wired network has a MAC address.  MAC addresses are used as a network address for most network technologies, including Ethernet and Wifi. No two devices should have the same MAC address.

Where can I download the Who’s On my Wifi detection agent?

What time period should I report sessions for?

In the Who’s On My Wifi installation, wireless users shall be considered unique client sessions per 24 hours, with unique clients being determined by MAC address. On the state report, libraries will report the number of unique daily sessions for the entire year.

How is the data masked?

Each Who’s On My Wifi agent that sits on a network to gather device inventory has a unique encryption key as part of the software that neither the company nor the State Library has access to in our cloud service.  If the Privacy Feature of the agent is enabled by the library, two important privacy things happen.  First is that all patron MAC Address information is 1- way encrypted using the unique per agent encryption key.  Second is that identifying information like the Hostname is replaced with the word PRIVATE.  Both of these things occur before the information is sent to the Who’s On My Wifi Online cloud system meaning that Who’s On My Wifi doesn’t have access to the original identifying information.

How does Who’s On My Wifi handle multiple VLAN segments?

Each Who’s On My Wifi agent is by default set to scan a single subnet or single VLAN.  Often when libraries have several VLANs, the VLANs are segmented between private networks that library personal utilize and a public VLAN that patrons utilize.

If there are several public patron VLANs, then you have the option of placing a single agent per VLAN, or there are ways to have a single agent scan multiple VLANs using a multi-homed computer as well, but this is often the exception to the rule.
