There are more than one billion websites available online. Many are useful tools for attorneys, so it makes sense to review and refresh your favorite bookmarks regularly. While none of the many free sites offer the sophisticated search abilities of fee-based research services, a few minutes spent exploring free sites can help researchers significantly narrow their searches once they turn to a fee-based system. Remember to always take advantage of the advancesearch option when available on a free site. Free sites are offering increasingly sophisticated search options, such as Boolean and proximity searches, which were previously exclusive to paid services.
