A catalogue standard makes the distinction explicit
The Library of Congress MARC bibliographic format has a field for a title translated by the cataloguing agency when that translated title does not appear as a parallel title on the item. Its title-field guidance also distinguishes several functions of title information. A helpful English rendering in a record therefore need not be wording printed or displayed on the work itself.
This is an explanation of catalogue data, not a claim that every streaming guide uses MARC or that every translated title is unofficial.
Separate title, language and edition
Copy the title exactly as the publisher presents it, including the original-script form if available. Record any translated or alternate title with its source. Then match the author or director, original year and format. A translated book, a screen adaptation and an episode discussing that book can share related wording while being different works.
A title’s language also does not establish the audio language. An English catalogue heading can describe a recording with another spoken language, while a local release title can accompany a dubbed edition. Check the edition’s language information separately.
Do not invent an official title by translating individual words and then assume a failed search means the work is unavailable.
Search with a traceable set of names
Start with the publisher’s title and a creator or year. Try documented alternate titles next, retaining the source of each variant. If a catalogue supplies its own translation, use it as an explanatory aid while keeping the original identification visible.
For a shared watchlist, store the displayed title, original title when documented, creator, year and exact publisher link. Label your own explanatory translation as your own. This avoids sending someone to a different adaptation or making a catalogue’s convenient wording look like a distributor’s release decision. It also leaves viewing availability as a separate check on the current authorised page rather than a conclusion drawn from one successful or unsuccessful title search.
An episode number or series heading can further distinguish a discussion about a work from the work itself.
