There is an official LibreOffice PPA here.
You need to add ppa:libreoffice/ppa

More information:

To add ppa and upgrade libre office using command line:

UPDATE 2
As of July 25th 2013, the following PPA offers the Release version of LibreOffice:
sudo add-apt-repository ppa:libreoffice/ppa
sudo apt-get update
sudo apt-get upgrade
That will leave you with LibreOffice 4.1.
UPDATE 1
A PPA is now available for 4.1.0. To add it, just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command(s) below:

ORIGINAL ANSWER
I have searched high and low, and I can't find a PPA for 4.1.x. Now if you would like to install it, (the documentation doesn't mention removing prior installation) I would recommend that you remove previous versions before installing this one.
To install LibreOffice 4.1.0 Beta 1 on Ubuntu 13.04, 12.10, and 12.04, do this. Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command(s) below:
For 32 bit systems:
wget -c dev-builds.libreoffice.org/pre-releases/deb/x86/LibreOfficeDev_4.1.0.0.beta1_Linux_x86_deb.tar.gz
For 64 bit systems:
wget -c dev-builds.libreoffice.org/pre-releases/deb/x86_64/LibreOfficeDev_4.1.0.0.beta1_Linux_x86-64_deb.tar.gz
Extract the archive:
eDev_4.1.0.tar -zxvf LibreOffic0.beta1_Linux_x86*_deb.tar.gz
Install LibreOffice 4.1.0:
cd LibreOfficeDev*/DEBS
sudo dpkg -i *
As of June 13, 2013 it still not available in the pre-release PPA. Once available will update the answer.

The main LibreOffice PPA is for "test builds and backports", including "alpha and beta releases!".
UPDATE As of 2016-07, I see it's "LibreOffice fresh", the latest release of the newest series (but no alpha/beta releases, which are now in separate PPA).
If you want less-bleeding edge, it includes links to per-version stable PPAs, e.g. https://launchpad.net/~libreoffice/+archive/libreoffice-4-1 for LibreOffice 4.1.
