Why search more than one journal database: ACS v. ScienceDirect

"Why shouldn't truth be stranger than fiction? Fiction, after all, has to make sense" -- Mark Twain

Why search more than one journal database? Simple answer … because they cover different journals. Take for example two journal databases, ACS Publications (http://portal.acs.org/portal/acs/corg/content) and Elsevier’s ScienceDirect (www.ScienceDirect.com).

The American Chemical Society (ACS) publishes Energy & Fuels, a journal that publishes many articles directly addressing desulfurization issues.

ScienceDirect is a database of journals published by Elsevier. Searching ScienceDirect for desulfurization article produces a rich list of journal articles, but that list does not include anything from Energy & Fuels, because Energy & Fuels is not an Elsevier journal.

There is a database the enables a nearly one-stop, comprehensive search of all the technical journals that might include desulfurization articles. It is the digital version of Engineering Index, hosted by Dialog (www.dialog.com). However, you have to pay a monthly fee to access this database.

If your company employs a librarian, you have at the very least indirect access to the EI database.

If not, you have to scrounge. Worst case is that you have to identify and search a number of individual online databases to be sure that when you research a topic, your results reflect everything that is available.

Here is a taste of recently published articles from ACS Publications and ScienceDirect.
