Linking Policy

This document outlines the policies for linking to the Texas Historical Commission (THC) website and
for requesting your link on the THC website.

1. Linking to the THC website: what you can do.
• You do not need to get advance permission to link to us if you are a historic preservation-related
site making a simple link to the homepage. However, we ask that you only link to us using the
following URL: http://www.thc.texas.gov
• We reserve the right to change web pages at any time without notice so we recommend you link
only to our main page and do not link to subpages.
• If you choose to link to a subpage, you must continuously verify your links to those pages.

2. Linking to the THC website: what you should not do.
• Please do not use our logo as a graphic to link to our pages. Use a text-only link with the words:
Texas Historical Commission.
• Please do not capture our pages within your frames or otherwise present our content as
your own. Any link to our site should be a link that passes the client browser to our site
unencumbered. The BACK button should return the visitor to your site if the visitor wishes
to back out. Although all content on our site is public information, the THC maintains and will
defend a copyright interest in these pages.
• You should not link to individual graphics or tables within our pages, especially in an effort to
place the downloading burden on our servers. Such an action may be considered a misuse of
state resources. To get permission to use a copy of our photographs or graphics within your web
pages, please contact thc@thc.texas.gov outlining your intended use(s).

3. Categories of links
• Links to county historical commissions or state and federal agencies related to our mission.
• Preservation partners or nonprofit organizations related to our mission.
• Definitive sources of preservation information of interest to our visitors.
• Links officially requested by state and federal agencies to preservation-related information.
• Note: Our policy is to not link to commercial websites. However, at our discretion, we will
consider a link to a commercial site if the content is of strong interest to our users.

4. Selection for links is also based upon such factors as:
• The frequency of requests for adding such a link.
• The stability and trustworthiness of the site.
• The quality and usefulness of the information.
• Links may be removed or replaced at any time without notice.

5. We will remove a link at our discretion if:
• The link no longer points to the original information or intended resource.
• The information is inaccurate or not trustworthy.
• Access to the information has become difficult due to odd formatting, lengthy download times, or
intrusive advertising.
• The link is gone or remains unavailable for a lengthy period, especially if we are unable to
contact you about your site?s status.
• We receive numerous email messages so please be patient while we set up your link. If your site
meets the standard criteria, we will usually create the link within 10 business days but it can take
longer. If the link doesn?t appear and you haven?t heard from us within two weeks, please send
your request again and mention that it is a second request.

6. Reciprocal links
The THC website does not enter into reciprocal link agreements. We provide links to sites that are
appropriate to our mission. Our creation of a link to your site does not obligate you to provide a link
back to us but you are, of course, welcome to do so. We always appreciate a note telling us of new
links. Send link information to thc@thc.texas.gov.
