Cengage and Cengaging textbooks have come under increasing scrutiny due to plagiarism allegations, with many of the books being widely used.

The company is set to launch the first major new algebra textbook in five years on Tuesday.

The book will be titled The Best Calculus textbooks for All Your Algebra Hacking article The title is not surprising given the company has been accused of plagiarism, with the first edition of its textbooks being used to breach a copyright in 2017.

According to the New York Times, the textbook was used to break into the Cengagers proprietary code.

Cengages founder and CEO, Alix Ravi, claimed it was the first time in the company’s history that its software had been used in a breach.

However, the Times has now learned that Cengaged has admitted to the breach, and it was found that the software was not even available in the first place.

“The problem was that we had to go back and re-architect the software and rewrite all the code to take advantage of this new tool called the CENGAGE API,” Ravi said in a statement.

“There were many different code paths we had taken, and I didn’t want to be the only one to use them.”

He added: “We have never used the code from CENGAGUAGE APIs to create a new program.”

The book’s first edition will be released on Monday and will be available on Amazon, iTunes, Kobo, Nook, Google Play, and other retailers.

It will cost $29.99.
