Anyway to open multiple instances of calibre?

[bookw0rm]

Anyway to open multiple instances of Calibre? I would like to open multiple instances of Calibre to view different libraries at the same time. Is there a way to do this?

[BetterRed]

The simple answer is No.

Curious - why do you want to do it? You may be able to achieve what you want using the server.

Also, FWIW
Find Duplicates plugin can Check another known (on the quick switch list) Library

I want to have multiple libraries open at once. How do I accomplish this in Calibre?

[ekbell]

I've put all my books (both ebooks and entries for paperbooks) into one Calibre library which is then subdivided into several virtual libraries which are then opened in tabs. Same effect as having several libraries while still being able to tab from one to the other.

How do you put libraries into other libraries? I have like 100 library tabs that I want to do what you're doing with.

Set up your master library(or whatever you name it) using switch/create library....; Choose your books; right click; select Copy to Library and choose the appropriate library name.

Make sure that you have some way of distinguishing between various virtual libraries (appropriate tags or whatever) before copying.

I can't say why bookw0rm wants to open multiple libraries at once, but I would dearly love to be able to have one version open because I'm searching the content and reading the books (and potentially updating metadata), and another version open where I'm loading new content.

For instance, have my RPG book library open while loading comic books into another library, or even have processes loading into my RPG book library and my comic book library concurrently. Possibly while I'm in my technical library.

Multiple tabs might make virtual libraries more capable than I realized, but I'm pretty sure they still don't let me load into one while I read another.

I wonder exactly what you mean by read? You can open a book from a library and continue reading it while you switch calibre to another library or even if you close calibre.

See the CalibreSpy plugin, it provides concurrent Read Only access to multiple libraries ==>> Index of plugins

CalibreSpy didn't exist when bookw0rm started this thread.

I've got CalibreSpy installed, but don't see how to activate it outside calibre itself... and haven't had time to look.

CalibreSpy might handle readonly access, but it's difficult for me to not fiddle with things when I find errors, and I use calibre in my workflow to track documents I've worked with, so I'd still like to be able to make changes in one library while loading into another.

I deal with this mostly by finding other things to do when I'm loading files... but it would be nice to have multiple instances open (via calibre GUI or calibredb) and manipulating different libraries.

[BetterRed]

AFAIK you can only be run ONE of these concurrently -- calibre.exe, and calibredb.exe, and calibre-server. And none neither of them can have more than one physical library open concurrently.

Have you looked at the .bat files in the first post for CalibreSpy, and read though the thread - post 37 might be of interest.

The calibre content server lets you manipulate as many libraries as you like simultaneously.

Very, very slowly.

When I run this script it takes ~4-5 seconds to load a file and set all the metadata I want (which is based on file location and other external information... GetFileName plugin did much of what I'm doing, but not all of it).

When I did a test run against a content server running locally, I could get maybe 3-4 files per minute.

I have considered going into the codebase and disabling the one-client-only check, and rely on my own sense to not run two against the same database concurrently, but this codebase bigger than I've had time to explore.

I have not, but I'll check in the morning. I just spent 16 hours struggling with a Cognos report. I won, but I'm tired.
