Our Use of Storage Technologies
Modern History Library (piiqq.com) uses cookies, local storage and similar technologies to support the operation of the catalogue and to improve your experience. This policy explains what types of storage we use, why we use them, and how you can exercise choice.
Essential Storage
Certain storage is required for the catalogue to function. This includes session cookies that maintain your browsing session and persistent cookies that remember your preference for viewing text editions. Without these, features such as remembering your reading position or retaining your cookie consent choice would not work. Essential storage does not require your prior consent.
Preference Storage
We store your choices about how the catalogue appears — for example, whether you prefer a larger font size or a particular display theme. These preferences are saved in persistent cookies or local storage and are used only on this site. Where enabled, these are set only after you have made a selection.
Analytics Storage
Where analytics are enabled, we use first-party cookies and local storage to collect anonymous information about how visitors use the catalogue — such as which pages are most frequently viewed and which search terms are used. This data helps us understand which editions and categories (for example, Revolutions or World Events) are of greatest interest. Analytics storage is non-essential and is set only with your consent.
Advertising Storage
Where advertisements are displayed on the catalogue, we may use Google advertising technologies, including cookies and web beacons, to serve relevant ads and to measure their performance. These technologies may be set by Google or by third-party advertisers and may involve both first-party and third-party cookies. Advertising storage is used only if you have consented to non-essential cookies, and you may withdraw that consent at any time.
Third-Party Cookies
In addition to the first-party cookies we set, third-party services (such as Google, where advertising is enabled) may place their own cookies on your device. These cookies are subject to the respective service’s privacy policies. We do not control the placement or duration of third-party cookies.
Session and Persistent Storage
Some storage we use is session-based and is deleted when you close your browser. Other storage is persistent and remains on your device until it expires or you delete it. We do not specify fixed durations because these may vary depending on the technology and your browser settings. You can manage and delete persistent storage through your browser’s preferences.
Your Choices and Consent
When you first visit the catalogue, you are presented with a consent tool that allows you to accept or decline non-essential categories (analytics and advertising). You may change your preferences at any time by accessing the consent settings link available in the catalogue footer. If you withdraw consent for a category, any related cookies already set will be deleted where technically feasible.
Most browsers also allow you to control cookies through their settings. You can block all cookies, delete existing cookies, or set your browser to alert you when a cookie is set. Please note that disabling essential cookies may prevent some parts of the catalogue from functioning correctly.
Local Storage
In addition to cookies, we may use HTML5 local storage to save certain preferences and interface choices. Local storage is stored on your device and can be cleared through your browser’s developer tools or settings. We do not use local storage to track you across other websites.
How We Use Data from Storage
The information collected through cookies and local storage helps us improve the catalogue's usability and tailor content to reader interests. For example, aggregated analytics may show that editions in categories like Social History or specific titles such as The Cotton Kingdom, volume 1 (of 2) — Text and Context are frequently accessed, guiding our editorial focus. We do not use this data to build personal profiles or share it with third parties for their own purposes without your consent.
Managing Storage Across Devices
If you use multiple devices to access the catalogue, your cookie preferences and stored data are device-specific. You will need to set your preferences on each device. We recommend reviewing your browser's privacy settings to manage storage consistently across your devices.
Changes to This Policy
We may update this Cookie Policy from time to time to reflect changes in our practices or for legal reasons. Any changes will be posted on this page. We encourage you to review this policy periodically.
