The US News & World Reports career website lists "what's hot, what's not", noting "what you choose to specialize in within a particular discipline can make a big difference in whether you can find a job".  Of particular interest to liberal arts majors:

ARCHIVISTS:

"This field will continue to grow dramatically for years to come as government at all levels, corporations, libraries, and museums put their records into an electronic format.  Archivists typically get training in the field of library and information science, where they learn how to evaluate the importance of documents and decide in which formats it is most suitable to store them." -- U.S. News & World Report

"Jobs are expected to grow as public and private organizations put more emphasis on establishing archives and organizing records and information, and as public interest in science, art, history, and technology increases." -- Occupational Outlook Handbook

ENGLISH AS A SECOND LANGUAGE TEACHERS:

"Some districts are offering extra pay to attract ESL specialists, who are in demand around the country because of the large numbers of immigrants in many school systems. Despite new restrictions on immigration, demand is expected to continue in part because so many children have come into the country in recent years."  -- U.S. News & World Report

"The number of non-English speaking students has grown dramatically, especially in California and Florida which have large Spanish-speaking student populations, creating demand for bilingual teachers and those who teach English as a second language (ESL)".   -- Occupational Outlook Handbook

INSTRUCTIONAL TECHNOLOGISTS:

"The White House wants to wire America's schools... Enter instructional technology specialists, who need not have teaching experience. Their work involves evaluating computer software and showing teachers how to use computer technology. Graduates, who typically hold degrees in library and information science, are also being hired by educational software companies and museums."  -- U.S. News & World Report

"Teachers may use films, slides, overhead projectors, and the latest technology in teaching, including computers, telecommunication systems, and video discs."   -- Occupational Outlook Handbook

INTELLECTUAL PROPERTY LAWYERS:

"Demand for these attorneys, who are involved in protecting the ownership of creative matter, results partly from the expansion of the Internet and the desire to use online material originally developed for other media. A New York firm raised the level of starting salaries last fall by offering $90,000 to lawyers with a background in science and communications."   -- U.S. News & World Report

"Continuing demand for lawyers will result from growth in the population and general business activities. Demand will also be spurred by growth of legal action in such areas as... intellectual property."  -- Occupational Outlook Handbook

PRINT JOURNALISTS:

"Aspirants may need unusual luck or talent to break into the field, at least in big-city markets. But those who opt for a job in new media--the online services most news organizations now offer--will find that there are many openings available."   -- U.S. News & World Report

"Small town and suburban newspapers will continue to offer better opportunities for beginners...  Talented writers who can handle highly specialized scientific or technical subjects have an advantage. In addition, online newspapers and magazines should continue to grow very fast and create numerous job opportunities".  -- Occupational Outlook Handbook

PROTESTANT CLERGY:

"More students are graduating from Protestant seminaries. But there are not enough congregations to hire them. The imbalance is expected to continue through 2005 because church membership is growing slowly. Experts in developing new churches and in youth ministry have the best prospects for finding employment."   -- U.S. News & World Report

The degree of competition will vary among denominations and geographic regions. For example, relatively favorable prospects are expected for ministers in evangelical churches. Competition will still be keen for more responsible positions serving large, urban congregations. Ministers willing to work part time or for smaller, rural congregations should have better opportunities."   -- Occupational Outlook Handbook
