P: Please add layflat paper offered by Blurb in Book module

The  'Send Book to Blurb' button uploads two PDF files (Cover and Pages) to your Blurb account for processing. You can also use the PDF Export function and upload the two PDFs manually on Blurb's website to your account, but the Lay Flat paper option requires  a new template that supports seamless two-page spreads. Until Adobe adds that support there is no way to create a book with Lay Flat paper using LR.

As I mentioned Lay Flat paper is supported using the Blurb Plugin with InDesign. You could also use the tools available on Blurb's website:

The easiest answer is Blurb didn't recommend this. Likely, it's because if one uploads a book you're still dealing with images - if it's a PDF the images have essentially "disappeared" into the PDF.

What about exporting the book made in Lightroom as a PDF then upload the PDF to Blurb? Will this then give the option for Layflat paper?

I badly require  BLURB LAY FLAT BOOK MAKING TOOL using LIGHT ROOM CLASSIC

I was so happy when I saw Blurb startet to make lay flats, but equally disappointed when I learned that there was no LR integration for this. The book module is essential for me when making books and it has made my life so much easier, so please, please add the lay flat paper as an option. 

I was disappointed to find that I could not have layflat pages for my Blurb book through Lightroom! Please add this for us SOON!!!

Please add the ability to access Blurb's lay flat books.

Thanks for the attention. I also communicated with Blurb who recommended my course of action.

I spoke to Blurb Tech Support on Oct. 19th concerning Layflat paper support in the LR Book module and their response is as follows:

"In regards to Lightroom, Adobe is responsible for the Book module within Lightroom. Blurb will be working with Adobe to see if they will add support for Standard Layflat Paper. To help encourage this, please visit Adobe’s Lightroom community page, and add Blurb Layflat Photobook Support as a feature request."

I sent Blurb Tech Support the the link to this post and I assume they have already contacted Adobe with the required information to add Layflat paper support in LR Classic.

I also spoke to them concerning updating the Blurb plugin for Adobe InDesign 2018. The plugin was updated shortly after our conversation and layflat paper layouts are now supported in InDesign CS3-6 and CC 2014-2018.

"I'm sorry to hear you're having trouble with the Adobe InDesign plug-in since you updated.  The good news is we're currently working on releasing a compatible plug-in for CC 2018 and I would suggest checking back later today to see if that has been updated."

Clearly - in full agreement. I get the feeling the Book module was a late thought as it doesn’t have the imagination of the others and I can’t recall any feature updates.
