Welcome to the eighteenth annual “Best Free Reference Websites” list. It is hard to believe that this project has been around since the late 1990s. In 1998, the Machine-Assisted Reference Section (MARS) of RUSA appointed an ad hoc task force to develop a method of recognizing outstanding reference websites. The task force became a formal committee at the 2001 ALA Annual Conference, and is now named the ETS Best Free Reference Websites Committee.

A link to this year’s list of winners can also be found on the ETS webpage along with a link to the “Best Free Reference Websites Combined Index,” which provides, in alphabetical order, all entries from the current and previous seventeen lists. Succinct and insightful annotations for the Best Free Reference Websites List entries were written by committee members in the years the particular websites were selected for the lists. These annotations provide guidance for using the websites as reference tools. Once again, the committee considered free websites in all subject areas useful for ready reference and of value in most types of libraries.

The committee has established the following criteria for nominations:

  • Quality, depth, and usefulness of content
  • Ready reference
  • Uniqueness of content
  • Currency of content
  • Authority of producer
  • Ease of use
  • Customer service
  • Efficiency
  • Appropriate use of the web as a medium

More detailed explanation of the criteria can be found on the ETS webpage (

As in previous years, the committee worked virtually, using email and the online bookmarking site Diigo ( Each member nominated five to seven websites using the criteria specified above and then wrote brief annotations that would assist fellow committee members with reviewing and voting for their favorite nominated websites. The goal of this year’s committee was to produce a final list with approximately twenty high-quality reference websites. It was a good year in terms of nominations. More than fifty websites were nominated and voting for the best ones was challenging. After careful review, the committee members recognized twenty-two new Best Free Reference Websites for 2016. The annotations for winning websites were edited by the co-chairs to ensure that they are of optimal use to librarians and fit the criteria listed above.
