Some of the online libraries I know are:
- Philippine eLib - Note that the government spent like 167 million for this project. The materials in the website, mostly are not for free if I'm not mistaken.
- Science.ph - The portal currently links to some 65 databases of various DoST sub-agencies.
I think the private sector should seriously consider in partnering with the DOST in coming up with a profitable win-win solution to make these highly-valuable information assets useful and sustainable.
