Frommer's travel guides are to cease in print format.
According to travel website Skift, Google, which owns the brand, has stopped production of the travel series, with the final titles released last February. Other books which had been scheduled have not appeared, and the titles’ authors have said they have been informed that they will not be published.
Some Frommer's authors reported being told that the books would be delayed before new contracts were signed, but all said that their books would not be appearing in print.
Google has not responded to requests for comment.
The technology giant bought the brand from John Wiley & Sons last August for $22m (£14.5) last year along with Unofficial Guides and an events guide, WhatsonWhen. Skift reports that the Unofficial Guide series will continue to operate separately.
Robert Nash of Stanfords, the travel bookshop in Convent Garden, said: “We have not been told anything about the series finishing. We stock quite a good range of them, and they do sell well.”
Last year only two Frommer's titles – The Day by Day Guide to Seville and The Day by Day Guide to Marrakech – sold more than 1,000 copies through Nielsen BookScan. Frommer's bestselling title ever has been the 2006 Day by Day Guide to Paris, which sold 10,950 copies, according to Nielsen BookScan.
The overall travel market has seen a huge impact from digital, being valued at £63.9m in 2012, 38% down from 2007.
Earlier this week it was revealed that Lonely Planet is to be sold by BBC Worldwide to US-based media company NC2.
