IANAL, but IMO, you have several points in your favor to argue that yours is "fair use":
1. You're not (I presume) making money from it
2. Part of it is news, which is more likely to be fair use than creative works.
3. The content is old and the quality is poor compared to today's standards.
4. The current market value of the content is not very high. It's not like you are publishing the upcoming Dune sequel. Current market value and whether you are taking away money from the copyright owner are considerations in determining fair use.
If you are actually setup as a museum or online library, I would think that would bolster your case even further that this is fair use.
As I said, I am not a lawyer and this is only my opinion. However, I do think people are much too quick to cave on these automated DMCA takedowns. If you do dispute it, what's the likelihood this Indian company or Sony is going to sue you? Whether you are willing to take that risk is of course your decision, but their entire operation would fall apart if everyone disputed their claims. It only works because everyone caves immediately.
