Information literacy is the ability to notice when information is needed, then find, judge, and use it well. Search engines handle the finding in seconds. The judging may be the hard part now. The term dates to a 1974 report by Paul Zurkowski, and the American Library Association fixed the modern definition in 1989.
That definition has barely changed, but the setting has. A card catalog offered a short shelf of options, while a results page offers millions, ranked in ways the searcher rarely sees. The catalog waited for a query. The engine volunteers an answer. The site's literacy explainers treat that shift as the central problem of the field.
The stakes are concrete. Journals that mimic real science while skipping real review can sit one result below genuine papers. The guide to how to spot a predatory journal walks through the tells. Telling them apart is information literacy in daily practice.
Where did the term come from?
The phrase first saw print in 1974. Paul Zurkowski coined it in a report for the National Commission on Libraries and Information Science. Wikipedia's entry on the concept, as updated in 2026, traces that origin. He led the Information Industry Association at the time. His worry was practical: new information tools demand new skills.
The American Library Association set the classic wording in 1989. An information literate person can "recognize when information is needed". That person can also locate, evaluate, and use it well. The Alexandria Proclamation of 2005 called the skill a basic human right in a digital world.
What does search change about the task?
A search engine collapses that work into a ranked list. Rank itself starts to look like authority. A 2016 framework warns against that shortcut. It came from the Association of College and Research Libraries.
Its first core idea holds that "authority is constructed and contextual". A top result, in other words, is not a referee's verdict. Six core ideas anchor the framework, from "information has value" to "research as inquiry".
What do classroom trials actually find?
The evidence is sobering. A 2025 study in Scientific Reports led by Martini and colleagues tested three classroom lessons. The trials ran in Northern Italy.
Some 2,288 students judged real Instagram posts on a phone-based platform. Overall skill did not significantly improve.
One lesson stood partly apart. Civic Online Reasoning helped a small subset indirectly. It taught "lateral reading" and "click restraint", the habits of professional fact-checkers. The inoculation lesson raised broad, generalized skepticism. For related coverage, see Reading aloud: the oldest literacy tool that still works.
That doubt also fell on sound science. A 2025 study in PLOS One led by Thomas Nygren tracked 459 upper-secondary students. Neither the Bad News game nor the News Evaluator workshop moved the numbers. The skill gains were not statistically significant.
How do researchers test these skills?
Both trials ran in real classrooms rather than labs. Students judged real posts and headlines before and after the lessons. The Italian team used an ecological design with phone-based delivery. The second study checked skills again three months later and saw no rise in verification tool use.
The reports are null results overall. That is honest bookkeeping, not proof that teaching never works. Two studies are a thin base. The Italian authors flag classroom distractions and varied engagement as forces that may mask small gains.
Conclusion
Search engines turned a scarcity problem into a sorting problem. The definition of information literacy has held steady since 1989. The newest trials report small, fragile gains. One popular approach left students doubting good science along with bad, while the habits that held up were modest: leave the page, check the source, and pause before the click. Attitude may matter most of all. In the PLOS One data, the study records, students who rated credible information as important were better at spotting accurate news.
