Cookie preferences

Cookies that are strictly necessary are always on — without them you could not sign in and forms could not be protected against cross-site request forgery. Everything else is your choice, you can change it as often as you like, and refusing costs you nothing but convenience. The cookie notice lists every cookie by name, what it does and how long it lasts.

Accept all cookies Necessary cookies only

Or choose category by category

Strictly necessary — always on Keeps you signed in, protects forms against cross-site request forgery, and remembers this choice about cookies. The site cannot work without them, so they are always on and no consent is asked for. Cookies: PHPSESSID, atrium_consent, zoomifyImageCopyright

Preferences Remembers display choices so they survive between pages: sort order, rows per page, interface language, whether empty taxa are listed, and the username on the login form. Without these, sorting and paging still work but reset to the default on each new page, and the login form does not pre-fill your username. Cookies: language, sort_type, page_control_number, show_empty_taxon, show_image_previews, show_collections_without_images, browse_levels, brit_username

Maps and embedded content Loads interactive and static maps from Google Maps. Sends your IP address to Google and lets Google set its own cookies. Declining replaces each map with a notice and a button that loads it on request. Cookies: NID, googtrans

How long this lasts

Whichever way you answer — yes or no — we remember it for 180 days and do not ask again in that time. A refusal is kept for exactly as long as an acceptance.

Global Privacy Control

If your browser or an extension sends a Global Privacy Control signal, we treat it as a refusal of everything that is not strictly necessary, without showing you a banner. We do not read the older Do Not Track header, which was never given a settled meaning.

Your privacy choices — California and other US states

Residents of California, Colorado, Connecticut, Virginia and other states with comparable laws have the right to opt out of the sale or sharing of personal information and of targeted advertising. Atrium does none of those things: there is no analytics, no advertising and no profiling here, so there is nothing to opt out of. The Global Privacy Control signal is honoured anyway, as a refusal of everything that is not strictly necessary. See the cookie notice for the full list.
