The omniscient USB stick – or how to carry Wikipedia in your pocket

Wikipedia is probably the most comprehensive knowledge database in the history of humankind. It’s just a shame when you can’t access it because your internet connection isn’t cooperating, eh? But it doesn’t have to be like this. You can download Wikipedia – and it takes up much less disk space than you’d expect.
We live in the age of information. Every discussion at the bar and every pub quiz question can be resolved with a Google search – at least theoretically. If you’re writing a paper or just curious about a topic, chances are you’ll also turn to the internet.
It’s certainly a fascinating thought that we have humankind’s knowledge right at our fingertips. But what if you need to look something up and have no internet connection? Here’s how you can carry the free encyclopedia with you without having to rely on the World Wide Web. It’s super easy.
Why should you download Wikipedia?
There are plenty of reasons why you might want to store the largest database of knowledge locally. For one, should there ever be a large-scale power or internet outage (knock on wood!), a copy of Wikipedia could prove quite valuable. Perhaps you’re abroad often and don’t want to waste your mobile data looking up every question that pops into your head.
Or maybe you like to go hiking in areas with poor network coverage and want to have access to a pool of important information at all times. You actually don’t even need a computer for your local Wikipedia.
Depending on what your needs are, a local copy of Wikipedia can take up between 4 and 40 gigabytes. You read that right – gigabytes. Not terabytes. And not even a hundred of them. In other words, you may even be able to download your personal Wikipedia directly onto your phone or onto a conventional USB stick to always have it with you.
How can you download Wikipedia?
In theory, you could download the collection of all Wikipedia articles directly from Wikipedia. These so-called dumps are updated every two to four weeks. Each dump is just over 6 gigabytes in size and contains all the texts from the English-language Wikipedia, but no images or media files.
But there’s a much easier option, which can take up even less space: offline readers. Here’s a selection of offline readers. They all work in similar ways, compressing, downloading and displaying the files for you. It’s child’s play!
Kiwix, for example, is available as an app for Windows, Mac, Linux, Android and Apple. All you need to do is download and install Kiwix; the rest of the process is self-explanatory. You can then download different versions of Wikipedia directly from the app.
For German-language Wikipedia, the smallest version is less than 4 gigabytes in size and only contains the introductions to all articles. If you want the entire content without images, the file is roughly 18 gigabytes in size. With all the images, the entire compressed version of Wikipedia takes up just over 41 gigabytes. Alternatively, there are also dumps sorted by subject matter, such as «computers» or «history». These are only a few hundred megabytes in size.
Now all you have to do is save the whole thing onto a USB stick, et voilà – your omniscient flash drive is ready!
The whole thing works almost exactly the same on a smartphone. Install the app, select your desired version and hit download. Admittedly, the Kiwix app isn’t exactly what I’d call pretty. That’s why, if you’re only looking to download select articles, I’d recommend sticking to the official Wikipedia app.
But surely Wikipedia is bigger than that!
Of course, these are highly condensed versions of the free encyclopedia. It’s difficult to say how large the entirety of Wikipedia actually is, especially as it changes practically every day.
Add in all pictures and media, and this figure becomes even more absurd. According to Wikimedia Commons, the uncompressed media files total over 540 terabytes. Good luck getting that onto your USB stick!
