5. ^¹ {{harvnb|Costanzo|1989|pp=145-146}}: "Writer's Workbench works primarily by counting and comparing. It counts the number of letters in a word (or words in a sentence) and compares the figures to established norms, then calculates a text's 'readability,' it's probability of being understood by a given audience. By matching the text against a data base of linguistic information, the computer identifies parts of speech, possible misspellings, and potential usage problems. The programming tricks for doing this are ingenious, but ultimately limited. What Writer's Workbench tells writers about the quality of their prose is based chiefly on quantifiable data."
6. ^^1 2 {{harvnb|Costanzo|1989|pp=157-158}}: "Kiefer and Sutherland polled students who used Writer's Workbench at Colorado State University, finding that student attitudes toward the program were positive, often enthusiastic (1984). They also polled participating faculty, who generally agreed that the program sensitized their students to the kinds of errors and stylistic weaknesses they stressed in their grading. But what about the quality of the writing? Reid and Findlay examined the relationships between holistically-scored essays and various stylistic features measured by Writer's Workbench (1986). They expected to find high correlations between the better essays and the more sophisticated elements of style, such as sentence structure, vocabulary, and parts of speech. Instead, the relatively simple quantitative measurements, like sentence length, word length, essay length, spelling, and readability, turned out to be more significant. This in itself is an intriguing finding. It suggests that the most important outcome of such studies may be what they reveal about our grading policies, not about our software."

Writer's Workbench was probably the earliest to be widely used on Unix systems. Then there were smaller systems with many similarities to Writer's Workbench that became available for the IBM PC in the early to mid-1980s."
10. ^^1 2 {{harvnb|Infoworld|1983|p=42}}: "Writer's Workbench (WWB) ... which was developed at Bell Laboratories, is actually a collection of 29 different programs that check spelling and punctuation, analyze writing style and provide information about principles of clear writing. The Writer's Workbench programs can be used separately, or they can be used as a group through the use of a single command.
The programs operate on ASCII text files and will return a wide array of information that breaks down into four categories: proofreading; style analysis; information; and 'utility' programs, which allow you to tailor Writer's Workbench to your own specifications...
[WWB includes] a program that will check for sexist usage of language and suggest alternatives. If Writer's Workbench finds the word manpower, it might recommend replacing it with staff or personnel."

13. ^^1 2 {{harvnb|Pfaffenberger|1987|p=183}}: "Style analysis programs originated in the research labs of the giants AT&T (Writer's Workbench) and IBM (Epistle). Writers Workbench got widely distributed during the 1970s and early 1980s because, owing to the government's prohibition (since lifted) on AT&T's entry into the computing market, it couldn't sell the software it developed (such as the UNIX operating system). AT&T therefore gave UNIX (often with Writer's Workbench) to many colleges and universities, and a generation of programmers and computer freaks grew up with it. Writer's Workbench, therefore, has inspired legions of programmers, who have developed personal computer versions of it."

It assesses the parts of speech in a document to 96 percent accuracy (equivalent to human performance on the same task). Nina McDonald, a psycholinguist at Bell Labs, did the majority of the other programming."
