URL-i protokoll calibre://

calibre registers itself as the handler program for calibre:// URLs. So you can use these to perform actions like opening books, searching for books, etc from other programs/documents or via the command line. For example, running the following at the command line:

calibre calibre://switch-library/Some_Library

Will open calibre with the library named Some Library. Library names are the folder name of the library folder with spaces replaced by underscores. The special value _ means the current library. The various types of URLs are documented below.

You can even place these links inside HTML files or Word documents or similar and the operating system will automatically run calibre to perform the specified action.

The URL syntax is:


This opens a window showing the notes of the specified item. The easiest way to create such URLs is to show the notes you want in calibre and click the Copy URL button to copy the URL to the clipboard and paste it wherever you need.

Here Field_Name is the name of the columns such as authors or tags. For user created columns, replace the leading # in the field name with an underscore, so #mytags becomes _mytags.

In addition to specifying items by id using Item_Id you can also specify them by name using either val_Item_Name or hex_Hex_Encoded_Item_Name. For example:


URL-i parameetrite kodeerimine kuueteistkümnendsüsteemis

Hex encoding of URL parameters is done by first encoding the parameter as UTF-8 bytes, and then replacing each byte by two hexadecimal characters representing the byte. For example, the string abc is the bytes 0x61 0x62 and 0x63 in UTF-8, so the encoded version is the string: 616263.
