PDF online

PDF has become an internet standard for documentation downloading. Its light in document size, cross platform compatable using clear simple viewing tools including zoom and search and its free (for the viewer). The only downside to all this is having to download the software from Adobe which can take an age on a slow connection and not much better on 'Big Pipe'. 

If you're stuck for time and/or resources and need a quick solution then a visit here is recommended.
