Best Free Reference Websites: Thirteenth Annual List
RUSA Machine-Assisted Reference Section (MARS)

RUSA Machine-Assisted Reference Section (MARS) contributing members: Amy W. Boykin and Kay Cunningham, Co-Chairs, Erica Danowitz, Matt Lee, Sarah Lehmann, Clark Nall, Donna Scanlon, Colleen Seale, Kristen Shuyler, and Alec Sonsteby

Welcome to the thirteenth annual “Best Free Reference Websites List.” 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 now it is appropriately named the MARS Best Free Reference Websites Committee.

Like previous lists, the 2011 list of winning sites is being published in this year's Fall issue of RUSQ. A link to this year's list is on the MARS 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 twelve 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 MARS webpage (www.ala.org/ala/mgrps/divs/rusa/sections/mars/marspubs/marsbestrefcriteria.cfm).

As in previous years, the committee worked virtually, using e-mail and the online bookmarking site called Diigo (www.diigo.com). The process went smoothly, especially given that several of the committee members have served on the committee for several years. 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-five to thirty high-quality reference websites. After careful review, the committee members decided to recognize twenty-five new Best Free Reference Websites for 2011.

Winning sites were notified electronically with a letter of recognition from the MARS Best Free Reference Websites Committee, and they were invited to link to the online version of this list. The annotations for winning websites were also edited by the co-chairs to ensure that they are of optimal use to librarians and fit the criteria listed above.

Biodiversity Heritage Library, www.biodiversitylibrary.org.

The Biodiversity Heritage Library is the result of the efforts of natural history and botanical libraries (including the Smithsonian, the Royal Botanic Gardens, Harvard University Botany, and others) to make accessible the “legacy literature of biodiversity held in their collections.” With 32 million+ digitized pages about plants and animals from publications from 1484 to the present, the site is available for anyone, though biologists, gardeners, and conservationists may find it most useful. Multiple searching and browsing options are available. The interface for browsing the digitized books and journals is easy to use, and the scanned images are of high quality and in full color. Well-designed and easy-to-use, BHL makes it possible to explore some of the world's great science libraries, museums, and botanical gardens.

Instead, the process is accomplished via statistical machine translation, a process that generates translations based on patterns found in large amounts of text. Quality varies by language. Already an amazing work in progress, Google Translate will undoubtedly improve with time.

The Mark Twain Project Online “offers unfettered, intuitive access to reliable texts, accurate and exhaustive notes, and the most recently discovered letters and documents. Its ultimate purpose is to produce a digital critical edition, fully annotated, of everything Mark Twain wrote.” This website makes the work of the Mark Twain Project, which has been ongoing since the 1960’s, freely accessible online.
