Customizing the booklet
The booklet was produced from the online-version via the command pdfjam --landscape --a4paper input_file -o output_file , where "input_file" and "output_file" are placeholders for actual file names. That is equivalent to pdfjam --landscape --a4paper --signature 0 input_file -o output_file which means that the entire booklet is in one signature. In the case of 56 pages (including covers), say, that would be equivalent to pdfjam --landscape --a4paper --signature n input_file -o output_file where "n" is 56 or any number larger than 56 which is a multiple of 4. (Note that the Magazine always has a multiple of 4 pages, so there will be no padding with blank pages.) The parameter --signature says how many logical pages fit into one stack, so if it is equal to or larger than the number of pages, that means that all pages are in one stack, so one simply prints two-sided, removes the pages from the printer, folds them, and that's it (optional: staple in the fold or bind in some other way).
Most people who want to print out the Magazine for proper binding will probably print out the "print version" since it has the traditional margin sizes. The "booklet version" is intended for those who want to save paper and don't care about margins, but probably want to produce just a throw-away copy for reading off-screen. As such, one stack makes sense.
Since all of the sheets are the same size, folding a large number will
produce noticeable "creep": the outer pages have to wrap
around the inner pages, so when folded will appear somewhat narrower
with the inner pages somewhat wider, causing them to stick out. That's
probably not a problem for a throw-away copy. If one would like to
actually bind that with less noticeable creep, then use something like
the command
pdfjam --landscape --a4paper --signature 8
The print version has all links produced by the hyperref package in black. They are still active, but not as obvious as links. Black looks better in a printed version, and of course the links have no function on paper. Since the booklet version is produced from the online version (since the latter is formatted to be the size of the traditional paper Magazine), it does have coloured links. That shouldn't be a problem for a throwaway version, but if anyone actually requests it, we can make the links black in the booklet version as well. Of course, one can print out the online version, which will usually scale to the page size, i.e., larger than the size of the traditional paper Magazine. Here as well, if anyone actually requests such a version with the links black, we can produce one.
