Our Use of Cookies

This catalogue uses cookies and similar technologies to make the site work reliably, remember your choices, understand how visitors browse, and—where enabled—deliver relevant advertising. This policy explains what cookies are, which ones we use, and how you can control them.

What Are Cookies?

Cookies are small text files stored on your device by your web browser. They allow the site to recognise your device during a visit (session cookies) or across repeat visits (persistent cookies). We also use local storage, which works similarly, to keep your preferences on your device.

Essential Cookies

These cookies are necessary for the catalogue to function. They enable core features such as navigating between pages, saving your selected display settings, and maintaining session security. Because these cookies are essential, they do not require your prior consent. They are typically first-party cookies and are deleted when you close your browser (session cookies) or remain for a short period (persistent cookies).

Preference Cookies

We use preference cookies to remember choices you make, such as your preferred text size, layout options, or language. These are persistent cookies that stay on your device for a limited time so that your settings are available on return visits. If you disable these cookies, some features may not work as intended.

Analytics Cookies (Where Enabled)

Where analytics are enabled, we use first-party cookies to collect aggregated information about how visitors use the catalogue—for example, which pages are most frequently visited, how long readers stay, and whether they encounter errors. This data helps us improve the site and understand reading interests. The information is anonymous and cannot identify you personally.

Advertising Cookies (Where Ads Are Displayed)

If advertisements are displayed on certain pages, we may allow Google and its partners to use cookies and similar technologies to serve ads based on your visits to this site and other websites. These cookies enable ad personalisation and measurement. They may be first-party or third-party, session or persistent. The specific technologies used include Google Advertising Products (such as Google AdSense or Google Ad Manager) where applicable. You can opt out of personalised advertising by visiting Google’s Ads Settings.

Third-Party Cookies

Some cookies are placed by third-party services that we use for analytics or advertising. These third parties may collect information about your browsing activity across different websites. We do not control these cookies, and their use is governed by the respective third-party privacy policies. Where advertising is enabled, Google is the principal third-party provider.

Your Consent Choices

When you first visit the catalogue, you may see a cookie notice that asks for your consent to non-essential cookies (analytics and advertising). You can accept or decline these categories. If you decline, only essential and preference cookies will be used. You can change your choices at any time by clicking the “Cookie Settings” link available in the footer of every page.

Withdrawing Optional Consent

If you have previously consented to analytics or advertising cookies, you can withdraw that consent by updating your preferences via the “Cookie Settings” link. Withdrawal does not affect the lawfulness of processing based on consent before its withdrawal.

Browser Controls

Most browsers allow you to view, block, or delete cookies through their settings. You can also configure your browser to indicate when a cookie is being set. Please note that if you disable all cookies, including essential ones, parts of the catalogue may not function correctly. Instructions for managing cookies are usually found in the “Help” or “Privacy” section of your browser.

Practical Effects of Disabling Storage

If you disable cookies or local storage entirely, you may lose your personalised settings, and some features such as persistent login or reading history may not be available. The catalogue will still load, but your experience may be less convenient.

Changes to This Policy

We may update this Cookie Policy from time to time. Any changes will be posted on this page. We encourage you to review it periodically.
