TrueFlix is a subscription-based literacy resource for schools and libraries and may be licensed for both on-site and remote access. A variety of methods are used to authenticate these accounts at your district, school or public library. If you are not integrally aware of your network or Web infrastructure, please review this information with the head of your technology department before making your decision.

1. IP Address: On-site access is most easily provided by authenticating the public IP address or address range (whichever is appropriate) unique to the subscribing institution(s).
2. Secure Referring Web Page: If your institution maintains a Web site that includes a page accessible only to your students or library patrons (using student ID numbers, passwords, etc. maintained by you), you can place a link to TrueFlix on that page and allow subscribers to access our service via that link..
3. One-time Password: If your institution shares IP addresses with nonsubscribing institutions and you do not have a secure referring Web page, we can connect you using the "one-time password" method. This method works well when one or more-but not all-libraries behind a proxy server elect to subscribe.

If you choose to subscribe to TrueFlix with remote access, there are a variety of methods to make this resource available to your students or patrons at home. You may already be using one of the methods below for other databases, including Grolier Online. If you are not integrally aware of your network or Web infrastructure, please review this information with the head of your technology department before making your decision.

1. Secure Referring Web Page: If your institution maintains a Web site that includes a page accessible only to your students or library patrons (using student ID nos., passwords, etc. maintained by you), you can place a link to TrueFlix on that page and allow subscribers to access our service via that link.
2. Library Card Authentication:  Library card authentication for remote access can be established provided that library cards are issued with at least three common starting digits and a fixed total length. The licensed site must also have its own web page.
3. IP Assignment: If you have the ability to assign an IP address to your remote patrons (possibly through a proxy server) we can authenticate those IP addresses for remote access. Please remember that we need to know the IP addresses you are assigning even if they are already authenticated. They need to be coded for remote access to ensure that your usage statistics can be gathered accordingly.

TrueFlix delivers videos and other content over the Internet. The number of videos that can be watched by a user simultaneously depends on many factors, including connection speed, the amount of other activity that is taking place on a school or library's computer network at a given time, and whether a school or library has a dedicated Internet connection or shares with other schools or libraries.

The following guidelines should be used to determine how many TrueFlix videos can be streamed simultaneously, and what implementation options for TrueFlix are most appropriate. Note that these are average usage guidelines only. Actual performance may vary based on factors listed above.

• Has your IP address or address range recently changed?
• Have you recently changed your Internet service provider?
• Have you added a proxy server or firewall to your technical infrastructure, either at your site or at the district (or other) level?
• Are you or your service provider using a cache engine?
• Have you added Internet filtering software to your system?
• Have you recently upgraded your technical infrastructure in any other way?
