There are many, literally hundreds of databases containing journal articles, conference papers, books, book chapters and other information sources. They can be found in Databases A-Z and on most Subject Guides on tabs titled "Finding Articles/Using Databases" and similar names.
There are far too many library blogs and ones related to the work of libraries and librarians to give justice to all of them. Some major ones are noted here. Please forgive omissions or recommend ones to be added to this list.
