Library Terms that Users Understand – a big survey of available data to show us that there ARE best practices as far as our users are concerned.
This site is intended to help library web developers decide how to label key resources and services in such a way that most users can understand them well enough to make productive choices. It serves as a clearinghouse of usability test data evaluating terminology on library websites, listing terms that tests show are effective or ineffective labels. It presents alternatives by documenting terms that are actually used by libraries. It also suggests test methods and best practices for reducing cognitive barriers caused by terminology.
Surprise surprise, the word periodical is confusing. So are words like database, pathfinder and Do-it-Yourself in Unicorn. [web4lib]
