Pocketbook PB740 collection support

This has been asked before - but the answers ("no support") don't convince me.

After many years with an Aura HD I moved on to a larger display (mainly for some needed pdf). After searching for some specs like SD-Card or "Collection"-support I ended up with a "Pocketbook InkPad 3" or internally "PB740".

This reader supports "Collections" (internal search name: "collection").

On the Aura HD I was able to configure the Calibre Kobo Driver to take a user defined column (say e.g. "#sammlung") as a cross reference value for the device data field. Thus any transmission from Calibre to the Aura HD updated the "collection" field in accordance with the Calibre data base. And the books on the Aura HD were categorized as "Collections" accordingly.

As the PB740 is recognized within Calibre, has a "driver" and supports "Collections" (on the device) I thought that the same functionality as with the Aura HD would be present on the Pocketbook.

Alas, it isn't.

The PB740 Calibre "driver" doesn't offer an option to crossreference a user defined column with the "collection" field on the device.

My hope is that the Calibre driver for PB740 could be adjusted on this matter.

Thanks for the great support to all Calibre developers.

The challenge is that we need to know HOW the device supports collections.

For instance Kobo eReaders store the info in a database that is accessible when the device is connected, and all that is needed is to update the database with the corresponding collection names.

On the other hand the Tolinos retrieve collection data from the location that the Epub is stored.

So firstly we need to know HOW the collection info is stored, then ideally a developer with the device needs to tweak the driver.

I'm pretty sure that all management functions are db-based (sqlite3).

But any further discussions seem meaningless as - for the moment - there seem to be no active developers with access to a PB740 in charge.

So, instead of using the PB740 with the current Calibre "driver" (in fact more like a stub), I'll keep using the Aura HD for any "serious" library access.

You'll find the books listed on a Kobo under "collections" now listed as "genre" in your Pocketbook. At least that's where Calibre sets them up in mine when I give them a tag like "History" or "Crime". The collections I think have to be filled manually, but the genre gets filled automatically - same thing as with the Kobo, just under another name.

No, I don't.

I'm using Calibres "tags" as catchwords/-phrases and per book there may be many of them. My Calibre library is on the top level (= virtual library) organized as "Collections" or "Book Shelves" and below that are all the other possible differenciations (Author, tags, publisher.....).

I could simulate this on the PB740 by using the "Folder" method (PB740 offers a folder view). I think it would even be possible to write a kind of function within Calibre that sends books into folders on the device based on the user defined column "collections".

But in the end this all would be not the same functionality as given by a device driver that supports this reader as good as on the Aura HD.

If you want to organise by folder, you can use the save template. The default is to create a folder for each author, but, you can change this to anything else.

To do that requires two things. Firstly, the collections on the device must be in a place that is accessible. They are on the Kobo, but, not on most of the other devices. Then you need someone capable of coding the plugin, or willing to learn. Having access to the device is pretty much mandatory to do this.

"...the collections on the device must be in a place that is accessible"

As written above: I think they are. There are two accessible db on the PB740 in contrast to the Aura HD, where one db (I suppose: the current book-values) is secured while the management db is accessible. The management functions and values for the user interface on the PB740 seem to be the db in a folder named "explorer-3" or something like this. I was able to skim both db with a freely available sqlite-Manager while the Pocketbook was connected to my PC.

"...access to the device is pretty much mandatory..."

My hope is that one of the developers will get to the Pocketbook series as successor to Kobo or Tolino devices in the future ;-)

That sounds hopeful. Though the database name seems a bit weird for what it is. Unless it matches the name of the application.

I don't see myself moving from Kobo, especially as the other devices are not readily obtainable here. But, if someone wants to send me one...

calibre is open source, you dont have to depend on one of the existing developers getting a pocketbook, you just need someone who knows how to code to get one and be willing to contribute an improved driver for it to calibre.
