Privacy Policy

The MBLC Website (or is the official website created by the Massachusetts Board of Library Commissioners (“MBLC”), an independent state agency. The establishment of the MBLC Website under the Massachusetts Library and Information Network (“MLIN”) was authorized by Chapter 85 of the Acts of 1994.

The following policy applies only to the use of the MBLC Website. In particular, please note that although some of the social media pages used by the MBLC might appear to be part of this website or of a webpage under the MBLC’s control, some of these sites are actually hosted by a third party provider. Thus when visiting these third party social media sites, you are subject to different privacy policies and terms of service. Please review the MBLC’s Social Media Policy to review more detailed information on our use for specific social media sites and for links to the relevant terms of service and privacy policies for those sites.

Your privacy with respect to the MBLC Website results from a partnership between the MBLC and you, the user. The Board of Library Commissioners endeavors to protect your privacy to the maximum extent possible. As a state agency, some information collected by the Board of Library Commissioners may be subject to disclosure to members of the general public under the M.G.L. c. 66 § 10, (the Public Records Law). Therefore we cannot assure absolute privacy. This policy informs you of the information that we collect from you at this site, and what we do with it, to whom it may be disseminated, and how you can access it. Based on this information, you can make an informed choice about the use of this site. You can maximize the benefits of your privacy partnership with the MBLC by making informed choices about whether to share personally identifiable information with us through this site.

Personally Identifiable Information. We use the term "personally identifiable information" to mean any information that could reasonably be used to identify you, including your name, address, email address, Social Security number, birth date, bank account information, credit card information, or any combination of information that could be used to identify you.

Your use of library resources on this web site, including library reference requests, or requests for subject information sent to the Board of Library Commissioners, will be treated with the same confidentiality as if the request had come to a public library. Thus, although it is important to note that the MBLC is subject to the Public Records Law, information that reveals the identity and intellectual pursuits of a person using a library is exempt from disclosure under the Public Records Law. M.G.L. c. 78 § 7 provides in relevant part:

That part of the records of a public library which reveals the identity and intellectual pursuits of a person using such library shall not be a public record as defined by clause Twenty-sixth of section seven of chapter four.

The MBLC also complies with the Fair Information Practices Act, M.G.L. c. 66A (“FIPA”) and with Executive Order 504, which are both discussed below, with respect to all personally identifiable information collected through the MBLC Website.

"Cookies" are files that a website can place on your computer. A cookie file contains unique information that a website can use to track such things as your password, lists of Web pages you have visited, and the date when you last looked at a specific Web page, or to identify your session at a particular website. A file allows the website to recognize you as you click through pages on the site and when you later revisit the site. A website can use cookies to "remember" your preferences, and to record your browsing behavior on the Web. Although you can prevent websites from placing cookies on your computer by using your browser's preference menu, disabling cookies may affect your ability to view or interact with some websites.

An "Internet Protocol Address" or "IP Address" is a series of numbers that identifies each computer and machine connected to the Internet. An IP address enables a server on a computer network to send you the file that you have requested on the Internet. The IP address disclosed to us may identify the computer from which you are accessing the Internet, or a server owned by your Internet Service Provider. Because it is machine-specific, rather than person-specific, an IP address is not, in and of itself, personally identifiable information.

"Social Media". A social media website is a website on a social media application that is usually maintained by an individual and has regular entries of commentary, descriptions of events, or other material such as graphics or video. A social media identity is a specific user identity that has been registered on a third party social media site and is associated with the Agency. Government social media sites or identities typically provide forums for commentary or news on topics related to the government agency that hosts the social media site or has secured the social media identity. A typical social media site (whether hosted by the Agency or a third party) combines text, images, links to other websites and other media related to the topic and enables readers to leave comments in an interactive format.
