I do understand your frustration! The only reason I mastered in IP (Although I would never work in the field) was because it was challenging to learn. Explaining it is just as hard!
I'm afraid that copyright in a literary work lasts until 70 years after the author's death (s12(2) CDPA 1988), so as nice an idea as the old articles are, it wouldn't help.
As the UK does not have a general defence of 'fair use' (Only acts such as research use that equate to fair use), you must show that your use falls under a protected catergory. These are:
s29- Research and Private Study
s30- Criticism, news reporting and reviews
s31- Incidental (or secondary) inclusion in a s30 work
As you can see, the questions I was asking was to attempt to determine the possibility of raising a defence, should it come to that.
Under s16, your use would fall under a breach on 2 counts:
s16(1)a- 'to copy the work'
s16(1)b- 'to issue copies of the work to the public'.
I don't want to make you contemplate suicide with the further statute details (of s17 & 18), but I'm afraid to conclude that your use of the work is a primary infringement of the author's exclusive rights, to which you have no defence. If you do feel that you could argue one of the defences named above on your facts though, please let me know which and I'll see if it would be possible. Other than that, any use of those articles could potentially render you liable to a lawsuit.
Hope that is an accurate enough overview for you. :-)
