In addition to the information resources purchased by the library, there is also scientific material published openly on the Internet. If you cannot find a certain resource in the collections of the library, it is worth checking if there's an open access version available.
Even if you don't have access to the library resources, you can still search the openly available publications.

Open access publishing can sometimes be delayed, ie. there can be an embargo. In these cases the article is first published in a subscription journal and only later openly.
