Vaheguroo Jee
Let's thank the sevaadaars who spent limitless time on this beautiful sevaa. Finding all the khajaanaa and then digitizing it for the internet must have taken forever. I think these guys are based in UK. May Guroo Sahibaan Bless Them!
Anyhow, Kulbir Singh Veer Jee, there is a download section at the bottom left hand side of the home page on the website where a lot of stuff is available for download. Also, you might have noticed a membership sign-up on top of the home page. Membership is absolutely free, and once you sign up, you are provided with further access to downloads including full books and literature. Most of it is either in JPEG images or PDF format for easy and mobile access. So yes, you can download almost anything, or even right click and save.
The site has been available for almost a year now. It was started around Vaisaakhee last year. It is regularly updated with new material. Apart from gursikhee related material, it's also very amusing to see old art pieces and works of literature.
