Great, I found the Library Maintenance button. Thanks so much.

This raises some new questions:

1) After checking my library, the majority of my books seem to appear in the Missing Book Format section. Does this imply that there was an issue when I migrated the location of the Calibre library to my external hard drive? Perhaps this confirms the suspicion that I have about "missing" books in my hard drive.

2) Is there a way to command Calibre to search for the missing books? Or is it better to simply delete the items in my library and re-import them?

3) It is still not clear to me what the purpose is of the "Fix Marked" command in Library Maintenance. The following instruction in Library Maintenance seems quite fatal: "Use this if you are not going to restore the formats from a backup." What does Calibre do if this command is selected -- delete them?

4) What is the ideal way to migrate an existing library as it is to a new location? I am confused as to the difference between the following two commands: "Use the previously existing library at the new location." And "Move the current library to the new location." Am I right in assuming that the latter command would be ideal as default for most people in normal contexts? When would the first command be preferable? Is a "previously existing library" based upon some memory of a library that Calibre has backed up?

5) I am using a Mac, not PC. Does this matter regarding whitelisting? And what are the scans that you are referencing? Are these security scans or scans by Calibre?
