 When converting to MOBI, calibre detects the *metadata ToC* in the input document and generates an end-of-file ToC in the output MOBI file. You can turn this off by an option in the MOBI Output settings. You can also tell calibre whether to put it and the start or the end of the book via an option in the MOBI Output settings. Remember this ToC is semantically a *metadata ToC*, in any format other than MOBI it *cannot not be part of the text*. The fact that it is part of the text in MOBI is an accident caused by the limitations of MOBI. If you want a ToC at a particular location in your document text, create one by hand. So we strongly recommend that you leave the default as it is, i.e. with the metadata ToC at the end of the book. Also note that if you disable the generation of the end-of-file ToC the resulting MOBI file may not function correctly on a Kindle, since the Kindle's use the metadata ToC for many things, including the Page Flip feature.

 The tags and authors fields have special treatment, because both of these fields can hold more than one item. A book can have many tags and many authors. When you specify that one of these two fields is to be changed, the template's result is examined to see if more than one item is there. For tags, the result is cut apart wherever calibre finds a comma. For example, if the template produces the value ``Thriller, Horror``, then the result will be two tags, ``Thriller`` and ``Horror``. There is no way to put a comma in the middle of a tag.
 
 The same thing happens for authors, but using a different character for the cut, a `&` (ampersand) instead of a comma. For example, if the template produces the value ``Blogs, Joe&Posts, Susan``, then the book will end up with two authors, ``Blogs, Joe`` and ``Posts, Susan``. If the template produces the value ``Blogs, Joe;Posts, Susan``, then the book will have one author with a rather strange name.
