Thank you NYC Librarian! Interesting article.
Without a doubt, the Lonely Planet guidebooks are not what they used to be!
I agree with Mardee.....When purchasing a new guidebook, I look to the Rick Steves guidebooks, Rough Guides or Bradts.
Absolutely the best, in my humble opinion.
Don't rule out older guidebooks. I have a Rough Guide to England printed in 2004. It's an excellent book! with great detailed maps of every region. It has a photo of Bodiam Castle on the cover and a quote from Bill Bryson (who knows a thing or two about books): "Rough Guides are consistently readable, informed and most crucially, reliable."
I have some Lonely Planet books which are--fortunately--older books, so are still in that time period when they were most excellent. The one I'm looking at now is a guide to The Lake District, pub date 2009.
DK/Eyewitness books are excellent. I'm currently reading England's South Coast, a DK/Eyewitness guidebook. (2023) This one was purchased at a "Friends Of The Library" sale for about 1/5 of what it would cost at a bookstore.
I have a Frommer's London (2009) and Frommer's England (2006) which have good information and maps.
A Michelin Green Guide to London (2018) which is in like-new condition and a great guide.
Bradt produces great guidebooks.....excellent guides by region. Right now I'm reading their Cotswolds book which includes Bath, Stratford-Upon-Avon and Oxford. Next I'll be reading their guide to Yorkshire, then their guide to Norfolk and Suffolk. On order is Britain From The Rails; A Window Gazer's Guide.
Time Out puts out guidebooks...or use to....the ones I'm looking at on my desk are Time Out; Norfolk and Suffolk (2010), Seaside Britain, Camping In Britain, 1000 Things To Do In Britain.
The "Let's Go" series of books was put out by St. Martin's Press. Their Let's Go London book (2008) is thorough, with good maps, geared more for young people (college age to early 20's) on their first visit.
Reading older books is not for everyone. Obviously, you must check out restaurants and hotels doing a Google search to see if they're still in business.....we all know that.....but you're probably going to be doing that anyway, whether you're using an older book or a brand new one.
I highly recommend checking out Ebay or used bookstores for older editions of travel guidebooks. Many are in like-new condition. The older books are not full of Instagram photos and little content like some new books being produced today.
One of the most enjoyable things to me is to spend an afternoon browsing in a used bookstore.
Don't miss your local library's annual "Friends Of The Library" sale. Great deals on used guidebooks that have been pulled from their shelves to make room for the newest editions.
