When I am in Lookup View (Person) how can I know which books correspond to the author so I can check update from the net the authors name in edit book view?
At the moments I copy then paste and search for the name in book view edit the authors of the book then go back and delete the wrong name in lookup view (person).
There are many crappy author names downloaded which need to be corrected.

You can use the "Show Books/Sections" command on the Lookup menu.

Also possible to use the explorer if you modify the PersonBrowse template: Right-click the explorer pane and choose Edit XSL Template to open this file in Notepad, then insert this code (red):

<xsl:text>Main</xsl:text>
<xsl:text> | </xsl:text>
<A HREF="BookList.xsl?Author={name}@xslparam:doctitle=Author: {name}" TARGET="_BLANK">Book List</A>
<xsl:text> | </xsl:text>
<A HREF="Person_Credits.xsl" TARGET="_BLANK">Credits</A>

Now you can click the "Book List" link to display the books written by this author in the Explorer window. To show the books in the Book View, right-click the Explorer window and choose "Show in List".

Note that you can also edit the author name from the Book View: In the 'Book Edit' window, right-click the author name and choose Edit from the popup menu.

Am I missing something here? In Lookup View (Person) clicking on "credits" will produce the same result.
