These are also a prime resource for researching your needs in the first instance. More expensive and restricted, in terms of content, is hardcopy Press which carry ELT advertisements. Also some professional journals carry some ELT jobs' information. In addition you may wish to approach government organisations such as The British Council and the USIA which have numerous posts worldwide at any one time. These organisations also regularly advertise their vacancies online and in hardcopy.
Recruitment agencies are another alternative.
Some may charge a registration fee but many offer their services free of charge to the teacher. Job Shops at Professional conferences are becoming a regular feature but again most, if not all, of the posts on offer are also advertised electronically on the Internet. They mentioned TEFL but did not say what one was. I myself would like a job in Hong Kong or Taipei.
