An alternative way to make your Calibre books available to Freda is to use Calibre2opds. It goes like this:

1) On your desktop PC, install DropBox (an application that creates a special folder on your PC that is, in effect, visible on the internet)
2) Install Calibre and calibre2opds, and follow the calibre2opds instructions (which, in short, consist of telling Calibre to put your Calibre library into DropBox's special internet-visibile folder).

Calibre2opds will create, in that special folder, a library catalog file. That file is in OPDS format (an internet standard for representing catalogs of books).

Then make a note of the URL of that catalog file, and enter that into Freda's "Library > Add OPDS Catalog" screen; you can then use that Freda screen to navigate around your Calibre library and add to your Freda library whatever book(s) you want. When you open one of these books, it will download onto your phone.

The calibre2opds manual gives more detailed instructions, with pictures.

This procedure will work for any OPDS-compatible book reader (not just Freda) - so you can use it also with Stanza and Aldiko, among others.

Provisos:
1) To access your library and download books, your phone will have to have a connection to the internet (so WiFi or an all-you-can-eat data tariff is recommended). Though once you have opened - i.e. downloaded - a book, you will be able to read it without using the internet, because Freda will cache it locally on your phone.
2) The procedure involves putting your Calibre library in a location that is visible to the world - or at least to anyone who can guess your DropBox user-id. You might not want to do that.
