Advantages of professional (student level) memberships (in computer science) I'm a sophomore undergraduate studying CS and I look forward to getting into research in future. Is there any advantage of being a student member of societies like ACM, IEEE, etc? I think it might help me expose myself more in the area of Computer Science and research in general but I'm still not sure. I realised that I already have access to digital library through my uni. How can I maximise the benefits I derive from my membership if I choose to become one?
For example, the yearly student membership cost of ACM where I study (India) is ~$25. It says:

Access to the full ACM Digital Library
Access to online courses, ebooks and training videos,
Electronic subscription to Communications of the ACM magazine
Access to ACM's highly targeted Career and Job Center
-Subscription to XRDS, ACM's all new student magazine
Electronic subscription to ACM CareerNews (twice monthly)
ACM e-news digest TechNews (tri-weekly)
ACM's monthly online newsletter MemberNet
Free &quot;acm.org&quot; email forwarding address plus filtering

I don't know how much these subscriptions really benefit me.
I can only address ACM. I would think that for an undergraduate, the benefits are small, though the fees are also very small. However, if you don't otherwise have access to the ACM digital library, a membership can come with a subscription (costs a bit more, though).
The digital library has just about everything published by ACM and its special interest groups, so is pretty valuable for research and some kinds of learning.
However, it is also likely that you university library can give you access for free, though it will be a bit less convenient as you have to go through a librarian.
There might be additional advantages if your university has a local student chapter depending on how active it is.
