What Are Cookies

Cookies are small text files placed on your device when you visit a website. They help the site remember your actions and preferences over time. This policy explains how cookies and similar storage technologies are used on this catalogue.

Essential Cookies

Certain cookies are necessary for the basic operation of the catalogue. These include cookies that enable page navigation, maintain session integrity, and allow you to access secure areas. Without these cookies, some features may not function properly. Essential cookies do not require your prior consent.

Preference Cookies

Preference cookies allow the catalogue to remember choices you make, such as your preferred display settings, text size, or language region. These cookies improve your experience by tailoring the site to your personal preferences. Where used, they are first-party and persistent for the duration of your session or a short period thereafter.

Analytics Cookies

Where enabled, analytics cookies collect anonymous information about how visitors use the catalogue. This includes which pages are visited most often, how users navigate between pages, and whether any error messages appear. The data is aggregated and used solely to improve the catalogue’s structure and content. No personally identifiable information is collected through these cookies.

Advertising Cookies

If advertising is displayed on this catalogue, advertising cookies may be set by us or by third-party advertising partners, including Google. These cookies help deliver advertisements that are relevant to your interests and measure the effectiveness of ad campaigns. They may track your browsing across different websites. Where advertising cookies are used, your consent will be requested before they are placed. You may withdraw consent at any time by adjusting your cookie preferences or by visiting the relevant opt-out pages provided by the advertising networks.

Third-Party Cookies

Some cookies may be set by services that appear on our pages, such as embedded video players or social media sharing tools. These third parties may use cookies to track your interaction with their content. We do not control these cookies, and you should check the privacy policies of those third parties for more information.

Session and Persistent Cookies

Session cookies are temporary and are deleted when you close your browser. Persistent cookies remain on your device for a set period or until you manually delete them. The duration of persistent cookies varies depending on their purpose. Essential and preference cookies are typically persistent for a short duration, while analytics and advertising cookies may have longer lifespans.

Local Storage

In addition to cookies, this catalogue may use local storage (such as HTML5 localStorage) to store data on your device. Local storage is used for similar purposes as cookies, such as remembering your preferences or caching data to improve performance. Local storage is not automatically cleared when you close your browser; you can clear it through your browser settings.

Google Advertising Technologies

Where advertising is displayed, Google may use cookies and other technologies to serve ads based on your visits to this and other websites. You can learn more about how Google uses data and how to manage your ad preferences by visiting the Google Advertising & Privacy page. Google offers a browser add-on to opt out of Google Analytics tracking across all websites.

Your Consent Choices

When you first visit the catalogue, a cookie banner will inform you about the types of cookies used. For non-essential cookies (analytics and advertising), we will request your consent before placing them. You may accept or decline these cookies. If you decline, only essential and preference cookies will be used. You can change your preferences at any time by clicking the cookie settings link in the footer of the site.

Withdrawal of Consent

If you have previously consented to the use of non-essential cookies, you may withdraw your consent at any time by updating your cookie preferences through the cookie settings link. Withdrawal of consent will not affect the lawfulness of processing based on consent before its withdrawal.

Browser Controls

Most web browsers allow you to control cookies through their settings. You can set your browser to block all cookies, delete existing cookies, or notify you when a cookie is set. Please note that disabling cookies may affect the functionality of this catalogue and other websites you visit. Instructions for managing cookies can usually be found in the help section of your browser.

Practical Effects of Disabling Storage

If you choose to disable cookies or local storage, some features of the catalogue may not work as intended. For example, you may not be able to maintain a reading list, save your preferred display settings, or see content that relies on embedded third-party services. Essential functionality, such as browsing and downloading public-domain ebooks, should remain available.

Changes to This Policy

We may update this cookie policy from time to time to reflect changes in technology, legislation, or our practices. Any changes will be posted on this page. We encourage you to review this policy periodically.
