Given your username and password, Secure login will be made through use the secure login mechanism. Then your entries are exported using XML-RPC and special backup commands.
The backup is then converted to XML and processed. All entries are sorted by year and month, created to a book of professional quality thanks to LaTeX.

I really think that there is ABSOLUTELY no reason to ask money for a PDF of your entries or selling your book (if you see what I mean). It should be provided to everyone. People who can donate give some money and help to bring the service to people who can't afford it or don't earn money yet.
LJBook converts your entries into another medium (and I hope you agree: nicely). So you get YOUR LJBook, with YOUR entries, and you do whatever YOU WANT with it (publish, sell, give, ...).
You hold the rights, it's YOURS! (but bandwidth is not yet free...)

Depending on the ressources needed for creating your PDF, you will be requested to donate after generating 2 or 3 PDFs. There is no minimum fixed (keep in mind that below 2 Euros, your donation is worthless because of fees) and any donation helps to keep running LJBook. Just after your donation has been received, you will have unlimited access to LJBook. Please understand that this service is resource consumming.

Here is a matter of trust. It is stated that passwords are NOT stored. The lowest risk (regard less of trusting this service or not) can be taken by changing your password BEFORE and AFTER using LJBook (links are provided for doing so). There is nothing logged except error logs, in order to improve the service. You can see the privacy statement for more information.

It was not possible to backup your journal. These error occurs when your encodings are not set properly or when your journal is not converted to UTF-8. It may also occur when servers hosting your journal can not handle the requests.
To solve this issue, you should check your encodings and that UTF-8 conversion has been made. If it still does not work, wait 5-6 hours and retry when servers hosting your journal should not be overloaded.
These issue is not due to LJBook.

All PDF are produced by pdfTeX which is part of TeX/LaTeX system. Now, let's take a look at the current TeX/LaTeX distributions.
You have got TeXLive which runs on any system and is about 600Mb big.
Then you got for Windows the MikTeX dsitribution which can provide you most of the things you need for about 250Mo. If you have some non-latin characters, you will have to add some components (+ 50 Mo)... etc...
My question is: do you bring to home the professionnal printer when you need it 3-4 times by year ?
Believe me, If I could have made it available on your computer, I would have...

This site is currently hosted on a dedicated server thanks to donors.
By donating, you will make it possible to rent a dedicated server with enough bandwidth to provide the free service and fetch all images from your journal. Free service with entries up to 1999, images and comments is offered because of donations. This features (specially comments and high-res images are very abndwidth consuming)
Donations make this service lives longer, and will help to rent a better server with more bandwidth.
Thus it will be possible to give access to this service to much more people. The aim is to make it enough well-know such that 1/10 users give a little something and make it runs completly free.

Currently, by donating you will be able to launch as many creation process as you want per hour and include high resolution images (even if there are too many users using the service). Thus you will have an archive. If you want, you will be listed on donors page.

I'm sorry to not offer these features for free, but the bandwidth required to fetch all images and sending back your PDF is too big.

It's up to you to decide how much you want to donate, there is no special amount requested for donors access. The only thing is to make an useful donation (below 1Euro everything is taken by PayPal).

The current blog sites supported are those based on LiveJournal. Administrators are contacted and asked if they agree my server to fetch XML files for you. They are free to refuse or not. If you want your LJ based site to be supported, just send me the email of the adminstrator.
Other blog systems could be supported (I just need an XML exporter), and any help would be appreciated! Join the SourceForge's LJBook project.

If you are using Acrobat Reader, you have got a little icon (a disk) which let you do it. Or you can select "Save a copy of" in the File Menu.
You can also use the link provided at the end of the creation process and right click on it, then selecting "Save Link As" or something similar.
The PDF produced is you own stuff, you do whatever you want with it, It's NOT limited, you can print, ccopy/paste, anotate it, ...

All text behind a LJ-cut is included. The only text not included, is the text in the tag: <lj-cut text="this text is not included"> .
So the lj-cut tag is ignored but not the text behind it.

Only free softwares (free like freedom), among them: pdfTeX, Lynx (a special hacked version), pdftk (a PDF toolkit, used here for encrypting), ImageMagick, libXML2, libCURL, and GNU/Linux plateform. See links for some more information.

At the end of the LJBook creation process 2 links are provided: one for the PDF and the other for the LaTeX source. This last one is provided only for Text Book (if you don't include images). The LaTeX source including links to images can be provided on request to donors.

YES! Thanks to marksmith who works at LiveJournal.com and took time to write a PERL script.

LJ Book is under development. The author will include comments, support for CJK/BIG5/UNICODE fonts.
The aim is to provide LJBook with high-res images to everyone and to extend it to other blog systems.
