Analysis of information sources in references of the Wikipedia article "Incremental reading" in English language version.
SuperMemo 99 made the first step towards efficient reading of electronic articles by introducing reading lists and the first primitive reading tools: extracts and clozes. Reading lists are prioritized lists of articles to read. Extracts make it possible to split larger articles into smaller portions. Clozes make it possible to convert short sentences into a question-answer format using cloze deletions.
SuperMemo 2000 greatly increased the efficiency of reading by introducing the concept of incremental reading.
