Using Calibre to move books from computer to tablet

May 22, 2015, 10:55 am

I have a Nexus 7 tablet and have used Calibre without any problem to load books from my computer and transfer them to my tablet after converting them into e-pubs. Now that I switched to Windows 8.1 and use Calibre, the books transfer but the tablet no longer recognizes them as books. The file shows up as a square with a question mark and when I open it I'm asked about what program I want to use to open this file, text, FB reader, etc. I did not have this problem with Windows 7. Is there something else that Calibre needs for Windows 8.1? I just dug out an old Windows 7 computer and tested a Kindle book (non-DRM) I had bought last night and had no trouble converting the file to an e-pub, transferring it and having the tablet recognize it as an e-book in ES File Explorer.

Thanks for any help with this.

Merge existing formats into New records when adding new books

May 22, 2015, 11:01 am

This may be a request for new functionality, unless someone chimes in to show me how I can do this.

What is needed -

The ability when adding new books to keep the new book metadata and all it's book formats, but when duplicate books are found in the existing library, then ONLY pull book formats that do not exist in the new records.

Why would we need this -

there are times when I want to add new books where I know the metadata is better and maybe the book formats are cleaner than I had, but I don't want to lose a format I had in the existing records that is not in the new record.

Another example is where I buy a new series of books that have the series perfectly setup, I have duplicates of those books, but the series is all messed up. The new books I'm adding are only epub and my exisitng books with messed up series is mobi. I want all the metadata from the new books I'm adding to be what I end up with and merge the mobi from my duplicates.

What I have to do now to accomplish this -

simple example:
I want to add the perfectly structured Authur C. Clarke's Space Oddessy - 4 books.
I have existing 4 books in my library but series is not there, the covers are older and a lot of metadata is missing are not right, titles namescontaining series, etc. The existing format is mobi and some have epub, but they are many years old and those epubs are not all clean.

the new books I'm adding are perfectly formatted, series are named right and in order, covers are up to date and all metadata is much cleaner and format is epub, the epubs are formatted much better.

1) I add the new books (without automerger, to preserve the older records to get their epub formats manually). I now have four duplicates.

2) I right click on a new added book, series 1, and select similar books by author - only Authur C. Clarke books showing to keep it easy to work with.
3) I sort by series (my four new books are together)
4) I highlight the first book in series, then click the title column heading to sort by title. (this shows my first book in series right next to my existing book, 2001 in this case - new clean record and old record)
*****
5) THIS STEP is my main goal in my manual process - MY new record, series 1 book is highlighted and holding the control key, I highlight the existing old duplicate book). This now keeps all the metadata of new book and epub of new record, and adds only the mobi format from my old record and deletes that old record.
******

Please don't say I can highlight the old records and easily edit in bulk the series, or use the series manager, etc. I know that. I also know I could bulk update with download covers and metadata.

The above example was a very simple example. A common case is where I will be adding a couple thousand books with many series updates, better metadata, cleaner formatted books, etc.

Bottom line of goal -

I want to use everything the new book record has - metadata and book formats and ONLY add missing book formats of DUPLICATE records to the new record and delete the old record.

My proposal for new Calibre enhancement -

Preferences/adding books
checking the: automerge books if they already exist in the Calibre Library
add a new drop down: "Keep the new record metadata and formats and add only missing formats from duplicates".

-------------
Thanks for bearing with me on this. If I'm totally missing a way to do this, I'm sorry and please inform me. I really doubt I'm alone on this. I think this would be a powerful feature as a lot of us have library full of old records that could be cleaned up with such a feature. I hope Kovid will consider this!!!

More content server questions

May 22, 2015, 1:24 pm

I have been playing around with my content server, and thought to try one of my virtual libraries instead of the whole content.
I have found something a little strange, which I cant quite understand.
So, if I have my CS set as default, ie not applying any particular virtual library, and then press the test server button, I get a browser page open, and I can access all my content. If I leave this page open, but then go back and change the server settings to point to say, one of my virtual libraries, and then stop/restart the CS, press the server button again, I get a second browser page open, but this time, I just have access to the appointed virtual library.
However, if I go to the first browser page (the one that showed my full content), it still allows me access to all of my content, even though it has the exact same address as the newly opened one, which is restricted to the one library.
I hope this makes sense….
So, is this a glitch, or a security issue, or just the way things are supposed to work?
Thanks.

Autopopulate a custom column from specific tags already in place

Probably an easy fix, but how can I make a colum that auto populates from specific tags? I have tags (ITC, NITC, Read, etc.) that I would like to be isolated into their own colums. I have already made the colums and if I want them to be populated, I have to enter the info individually. I suspect this falls under information taken from other columns, but I have yet to figure out how that works.

Can one send books to a new Kobo reader from calibre, without using any of the Kobo add-ons - drivers, plugins.

My neighbour, a non-English speaking +70 year old, got caught up in the IOS problems last year and he stopped using calibre. He likes calibre but he doesn't want a repeat of the IOS problems. His granddaughter has suggested she buy him a Kobo.

Auto sync News to subfolder?

May 22, 2015, 6:00 pm

I'm playing around with the Connect To Folder feature and I first made a test folder and connected to it in Calibre. Immediately Calibre made a subfolder called "calibre" with all the magazines in my News category synced there. I was not expecting this but was pleasantly surprised. I was able to sync the rest of my books to the parent folder I selected (see image below).

After doing this test run I made a fresh folder in my Dropbox to sync to that. However, Calibre didn't sync my News items nor create the 'calibre' subfolder this second time.

I'm just trying to figure out, is there something I accidentally did/have to do to turn that on?

Is there any way to get other groups of books to sync into their own subfolder like it did with News magazines so I can maintain some physical organization when I open the folders in my iPhone Dropbox app instead of a flat list of books or authors? (like one folder per genre or rating)

Here is an image showing what Calibre did the first time:

How to access metadata in books synced through Connect To Folder?

Those of you using the "Connect To Folder" feature to sync books, how are you actually using and organizing your books on the destination device since there's no metadata.db or OPDS file?

I've used Connect To Folder to sync many of my books to my Dropbox for iPhone access. It's a bit hard to navigate this huge list of books on the iPhone Dropbox app without my metadata, though. I tried to create an OPDS file/server with calibre2opds but it can't because there is no metadata.db file. There is a file called ".metadata.calibre", is this the same thing as metadata.db with a different name? Even if it is I don't see any way to tell calibre2opds to use it. Is there any way to make an OPDS?

If not, is there any other way to create some organization or access the metadata or create a proper metadata.db file for the folder?

Unable to Open Books After Windows 8.1 Reinstall

I maintain my library in a OneDrive folder. I have had Calibre installed on a MacBook Pro and a Windows 8.1 machine, both pointed to the OneDrive folder. All has been stable for some time. Recently, however, I had to reinstall Windows 8.1 on the Windows machine. After the reinstall I deleted any lingering Calibre settings from the machine (e.g., in App Data). I then did a fresh Calibre install on the Windows machine and ran through setup pointing the new installation to the OneDrive folder. It completed and lists all the books, but I can't access any of them. Whenever I click on a title, I get an error message with the details below. Everything continues to work fine on the MacBook. I'd be very grateful for any suggestions on how to remedy the problem. I can access the OneDrive folder and open the files it contains on the Windows machine--just not via Calibre. All books are DRM-free.

Here are the error details reported by Calibre:

Calibre Keeps Crashing?

I've used Calibre for a few years with no problems, love the program.

Now, though, every time I load up Calibre, it comes up with the windows error message, stating that Calibre has stopped working.

About ten minutes ago, it started saying that it could not communicate with my Kindle Fire HD, however that error message has stopped, and now Calibre simply crashes after about fifteen seconds of being open when my Kindle is connected.

How to change Author format in metadata for saved PDFs?

Currently, when I save an ebook as PDF from Calibre, the metadata for "Author(s):" is written as "{authors} [{author_sort}]".
I would like to change this simply to "{authors}" and have the "{author_sort}" in a separate field, with the field order outputted by ebook-meta preferably as

Title:
Title sort:
Author(s):
Author sort:
Publisher:
...

I have searched high and low for a description how to achieve this, but no luck.
I appreciate any help on how to do this!

Hard Drive crash, can't new library working

The hard drive that contained my Calibre library crashed. I had it backed up on another drive, but when I run the Welcome Wizard on the new replacement drive it fails saying “an Invalid library already exists at M:\E-books” and that I should delete it.

“Error : NotADBError :file is encrypted or is or not a database.” I tried both the Metadata.db and the backup.

I’m guessing that the Metadata.db doesn’t exactly match what is currently in the library. I don’t know when the backup was made, it could be several days (or more) old.

I have over 600+ directories of books and I don’t want to enter them manually. Is there any way to use that old Library to start a new library on a new hard drive?

Published Date will not change in metadata editor.

I'm running Calibre 2.27 and I'm having an issue with the "Published" field. I want to be able to sort all books by a particular author by date, but a few of my epub files don't contain a publishing date field. I can open the calendar pop-up in the metadata editor but no matter what date I set it defaults to the current month and year. I've tried this with several books and always get the same result. I've noticed that epub's that do contain the field also can't be changed. What is the problem here?

Is there some setting I'm missing that enables this action? It's very annoying to have 80% of my books sorted, then a few stragglers that refuse to cooperate.

Any help would be greatly appreciated.

Why did the Date Column change and is it going to change back?

May 24, 2015, 5:39 am

Hi. It used to be that the date column reflected the date I added an ebook to Calibre, regardless of the existing opf file. This way when a friend lent me a book, my Date reflected when I added the book and not when she had.

I searched this forum to find out what was going on and I came across an old post from 2011 (link: http://www.mobileread.com/forums/sho...ook+entered%3F) that relates to this subject.

One of the responses from kovidgoyal was:
"Yes the original behavior was to update the date field from epub metadata and it was removed later."

In response to someone else's post, who said:
"My (often faulty) recollection was that originally the Calibre date field was the date the book was added, unless the the Calibre date was specified in the epub opf. This confused some people, who expected to always see the date the book was added, not some date stored in the opf, so it was changed to ignore that date on import? Then again, perhaps my recollection is wrong? This wouldn't be a change of date, but it might explain why you recall it as not always being the date the book was added?" - (Originally Posted by Starson17 View Post)

So my question is why was the date column changed back to the "original behavior" and is there a way to go around it? (I now have Calibre ver 2.28; 64-bit/Win8) THX

Mass metadata enhancement

I routinely add very large number of items to my database at once but rarely use the "add in bulk" function since I'm very particular about the selections (auto mode often picks the wrong meta/incorrect book version/etc) ..

I was just thinking how cool it would be if you could select, say, 100+ books to process and it could do the time consuming work of downloading all the potential data entries/cover image options, etc) -- When it gets done, you could just go through and pick all the appropriate choices like you normally do when you add 1 at a time - but not have to wait on remote server on each book. Would be a huge time saver, as opposed to how I usually do it.

Perhaps I'm just going about it wrong in the first place- I'm still a novice user who hasn't spent a whole lot of time digging in deeper to see if there were any advanced features or plugins that would speed up my process. Any suggestions would be much appreciated. (I currently have around 45,000 books in two Calibre libraries, the majority being public domain material.

Tips for finding high res book covers

Just upgraded to a 4K monitor last month so I've become a lot more insistent that my ebooks have the highest quality book cover art I can find -- I just happened upon a very awesome source I thought I'd share in case some aren't aware of it. If anyone has any other locations to share, would much appreciate it :)

http://www.penguinrandomhouse.com/
Just search for the book and click "enlarge cover" button -- It will then give you the option to download high-res copy. The size averages 5-20mb each, varous resolution. (The 22mb one I just grabbed was 1621x2442)

I also occasionally hop over to amazon or b&n , find book and click it to give preview, then do a screen cap and quick crop in paint.. Between those 3 and all the sites calibre searches, I'm rarely stuck with a low res cover anymore. Takes a little work but worth it imo, as I love my eye candy ;)
