What you see here is (my first attempt at) an overview of The Official UK Playstation Magazine (one of the many as displayed at the bottom). In the top right you will find the most prominent Silent Hill issue (hence the SH cover) and underneath a little colour legend. When you hover over issue 48 (digitally archived), you will see the magazine cover and the relevant material (missing from the photo), which will include a link to the actual scanned (hi-res) content.
Below the issues are the most relevant details about the magazine itself and underneath you fill find photos of the Specials.
This way it is easy to spot which magazine is missing from the archive. And while searching for content, I do take in the fact that Silent Hill 1 was released in the beginning of 1999, so it's most likely to find content around that period, although some games have had an extensive (pre) production process, so you really never know what to find in which issue!
