There are a number of placement companies in the regional area that can help you find a permanent or temporary job.They are listed on the SC&I Placement website under "Sites with Job Listings" (http://comminfo.rutgers.edu/placement/links.jsp). Among them are Infocurrent, The Library Co-op, Pro Libra Associates, and Wontawk.
For jobs in other parts of the country, job hotlines may be useful. These are printed occasionally in American Libraries in the section containing position announcements. Some examples are:
California Library Association -- 916-447-5627
Medical Library Association -- 312-553-4636
New England Library Jobline -- 617-521-2815
Special Libraries Association -- 202-234-3632
Job listings on association Web sites are becoming ubiquitous. See, for example, http://www.aallnet.org/committee/placement/listings.htm for law library position announcements.
