The Virtual Library CDN

 

The Virtual Library CDN contains a backup copy of all books hosted on TheVirtualLibrary.org

The contents housed in cdn.thevirtuallibrary.org are accessible through The Virtual Library PDF Viewer, a self-developed web viewer optimized for almost all devices and developed using the pdf.js library of Mozilla Firefox available on Github.

The Virtual Library PDF Viewer can be a useful tool in many cases as it provides tools not available on all devices. Searches can be made on documents (even in many image-based facsimiles) and sources are optimized for better readability. It also provides thumbnails for each page, access to the content index (when an index is available) and a button on the right side allows to download the book.

Connections are made on port 443 by default (SSL) but insecure connections on port 80 are allowed as well.

 


 

To access the contents hosted on cdn.thevirtuallibrary.org a simple url scheme is used:

 

https://cdn.thevirtuallibrary.org/web/viewer.html?file=/bookID.pdf

 

bookID parameter must be replaced by the ID of the book in The Virtual Library website.

 


 

Example:

This URL contains the book of Poetics of Aristotle: https://thevirtuallibrary.org/index.php/en/books/major-collections/book/aristotle-collection-307/poetics-de-poetica-758

The Book ID is available in the page (below the Title) and also at the end of the URL: (ID = 758)

The book in CDN can be accessed through this address: https://cdn.thevirtuallibrary.org/web/viewer.html?file=/758.pdf

 


 

More than one book under the same ID:

Many books in the library contain different volumes under the same ID. In these cases, the different volumes are labeled following a simple numerical order: 758, 758-2, 758-3, 758-4, etc.

Example: This URL contains the book of Poetics of Aristotle: https://thevirtuallibrary.org/index.php/en/books/major-collections/book/aristotle-collection-307/poetics-de-poetica-758

That URL contains two different copies of the same book. On the one hand there is a standard PDF version and on the other hand a PDF facsimile.

The first book in CDN can be accessed through this address: https://cdn.thevirtuallibrary.org/web/viewer.html?file=/758.pdf

The second book in CDN can be accessed through this address: https://cdn.thevirtuallibrary.org/web/viewer.html?file=/758-2.pdf

It will continue in the same way if there are more books to download from the same ID: -3, -4, -5, -6, ... etc.
