There are a number of places to look for jobs in anthropology (and related fields) — all disciplines have their own outlets, although some of these are fairly general (as in the Chronicle).
This is the catchall for anthropologists, and most jobs in anthropology — tenure track or not — are listed here. But not all jobs are, in part because it costs money for people to place ads on each of these sites. So many schools with limited budgets will only post on 1-2 sites they think will reach their audience.
The British (and European) job market is a little different than the US and Canada — it starts in late spring, and moves much more quickly. Anthropology positions are often in non-Anthropology — but social science — departments.
Chronicle of Higher Ed
