This is almost certainly due to Calibre.

As much as I like Calibre, it did do this 'hundreds of collections' thing to me also.

There are two main issues here.

1. When adding titles into Calibre, it imports or downloads way too many metadata tags.

2. When you send the files to your Sony, these tags get converted to collections.


Calibre has several options that control how files are tagged when added to your Calibre library.

Unfortunately, the options that control tags are splattered all over the place -

Under "Behavior"

- Overwrite author and title by default when fetching metadata
- Download social metadata

Under "Adding Books"

- Read metadata from file contents rather than file name

The above options will control how many tags, if any, that Calibre creates when adding files.

Once Calibre creates the tags in it's internal library, conversion of these Calbre tags to Sony reader collections is controlled by yet another set of options -

First the metadata is filtered through the "Metadata plugboards" (should be no problems here if you didn't change anything)

Then the conversion to actual collections on the reader is controlled by -

Preferences -> Plugins -> Sony Device Interface

Be sure to pick the 'Device Interface' plugin, NOT the Sony Output plugin (which is probably what most people would guess).

Under the Sony Device Interface plugin's options you will see an option that controls tag to collection conversions.

If you don't care how many tags Calibre creates internally, but DON'T want Calibre to create ANY collections on your Sony, the Sony Device Interface Plugin options are where you can fix things.

This has changed with recent updates to Calibre, so older versions in Linux or Mac OS look different, but ALL versions have the potential to cause problems by sending too many tags to the reader as collections, depending on how they are set up, so I have disabled this feature entirely, and just create my collections manually on the reader.
