If you are using a public web server then they will normally tell you what URL should be used to access the files you have just uploaded.This will include the Calibre2Opds generated catalogs as a sub-folder of the location holding the author folders from the Calibre library. Copy your entire Calibre library folder to a location that is visible to the web server that you are using.The details of these can vary, but the following should provide some general guidance. Many users run web servers on their own home network, or alternatively make use of space on web servers that are provided by their ISP.

This would typically involve providing a username/password challenge or making sure the URL used is not easily found (which is what most “cloud” services use). Depending on where you live, failure to do so may mean that you are infringing copyright If you make your Calibre library visible on the public Internet then you need to make sure your books are not easily accessible by unauthorised users. Dropbox which is described here is an example of such a service, but it is far from being the only one available. This is the generic term used to describe facilities where you can have files that are located on your own PC or Mac replicated to servers on the Internet so that they can be accessed from anywhere.

This could be an ISP provided web space – but if this is the case please read the caution about controlling access. This can be your own private server, or one run by someone else on which you have space provided for you own web content. This will tend to break down into 2 distinct families of servers:

The method allows all catalog files and book files to be accessed as a path relative to that of the top level catalog file.

The method chosen provides a network path to the top level file in the generated Calibre2Opds catalog.

NOTE: If you are using calibre2opds in Nook mode then you do not need to publish your catalogs as they will have been copied (together with their associated eBooks) to the Nook and held there as local files To be able to use your generated Calibre2Opds catalogs you need to make them visible on the network.
