Deletion of Britannica (disambiguation)

Comment: Yes, they are all partial matches but I'm considering  further down MOS:D#Examples of individual entries that should not be created and also . The encyclopedia is certainly often referred to with the single word "Britannica" but is this not done for any of the other entries? I expect MV Stena Britannica is often called simply "Britannica" so I think the ship could be included (note also the set index MS Stena Britannica). On the other hand I doubt whether Pax Britannica is ever referred to as "Britannica". On the whole I think the page may well reduce confusion rather than add to it and that is what the guidelines are seeking to achieve
