Now for Creating a book in Wikipedia. book maker (Create a book) uses normal links to make pdf file. it is much better to have possibility to have pdf from Permanent link or stable version of articles and the users who created that books page can set it.
for example in
https://en.wikipedia.org/w/index.php?title=Book:Internet&action=edit

links are normal and they should be like this

:[[Internet]]
:[[History_of_the_Internet]]

instead of that it should be like below:

:{{book maker|Internet|oldid=584336312}}
:{{book maker|History_of_the_Internet|oldid=586241162}}
