This book is to show how the various OEB and Microsoft Reader tags are supposed to look in the .lit file format.
This particular book was built in the NON-OEB format, which will change how some tags behave. Those changes are noted throughout the book.
These few paragraphs are demonstrating the P tag. Each of these paragraphs has an opening P tag and a closing P tag, which is why there are line breaks at the end of each one.
