Journal packages are collections of full text journals produced by one or a group of publishers. The collections vary in size, from 12 up to more than 1800. For these reasons, you should start your search in a database, which contains articles from thousands of journals from different publishers. Then you can go to a journal package to find full text articles or to follow a favorite journal. The packages below are popular with scientists.
Proceedings are the official record of a conference, usually held by an association or organization. The proceedings may include contributed papers, abstracts of papers or presentations, and other types of documents. Articles or papers from conference proceedings can be more difficult to find than journal articles because they are not widely indexed, and often the official title of the conference is difficult to identify.
