SJA
From TARDIS Index File, the free Doctor Who reference.
The prefix abbreviation SJA stands for The Sarah Jane Adventures, a spin-off which takes place in the Doctor Who Universe.
It should refer only to episodes and specials of The Sarah Jane Adventures, rather than to non-television spin-offs of The Sarah Jane Adventures (novels, comics, etc.), should they appear.
It also should not apply to the separate spin-off starring Sarah Jane Smith, K-9 and Company.
