If you want to access the Watchtower Library on your mobile device, you may have heard of a file format called iSilo. iSilo is a document reader app that can open files with the extension .pdb. These files are formatted for mobile devices and can contain text, images, links and bookmarks.

One of the advantages of using iSilo is that you can have the entire Watchtower Library on your device without needing an internet connection. You can also search, highlight, annotate and bookmark the publications as you study.

However, iSilo is not an official app from Jehovah’s Witnesses and it is not supported by the organization. The Watchtower Library files for iSilo are created by volunteers who convert the CD-ROM version of the library into .pdb files. These files are not updated regularly and may contain errors or omissions. Therefore, you should always compare them with the official publications on JW.org or JW Library app.

Also, since 2014, the production of the English iSilo files has been discontinued. This means that you will not be able to access the latest publications or revisions with iSilo. Other languages may still have iSilo files available, but they will also be discontinued as JW Library app becomes available in those languages.

If you still want to use iSilo for your personal study, here are some steps to follow:

1. Download and install iSilo from the app store of your device. You will need to pay a fee for this app.
2. Download the Watchtower Library files for iSilo from a reliable source. You will need two main files: WTPub-XX-Full-YYYY.pdb and WTPub-XX-DX-YYYY.pdb, where XX is the language code and YYYY is the year. For example, WTPub-IT-Full-2012.pdb and WTPub-IT-DX-2012.pdb are the files for Italian language in 2012. You may also need some additional files for scripture links, such as RBi8-XX.pdb and NWT-Rbi8-XX.pdb.
3. Copy the .pdb files to your device. You can use a USB cable, a cloud service or a file manager app to do this. Make sure you put all the files in the same folder on your device.
4. Open iSilo on your device and browse to the folder where you copied the .pdb files. Tap on the file with Full in the name to open it. This is the main file that contains all the publications.
5. You can now browse through the publications by category, year or title. You can also use the file with DX in the name to access the index of topics, scriptures and publications. To go back to the main file, tap on the home button or on the Publications link.
6. You can also customize your settings in iSilo, such as font size, color scheme, screen orientation and navigation options. You can also use the search function, highlighter tool, annotation feature and bookmark manager to enhance your study experience.

We hope this article has helped you understand how to use iSilo for accessing the Watchtower Library on your mobile device. However, we recommend that you use JW Library app or JW.org whenever possible, as they are the official sources of spiritual information from Jehovah’s Witnesses.
