Why bother to know which journals there are - after all, a literature search, google, google scholar, will find articles by keywords anyway?

It is true that search engines have become better and better. However, particularly when one is looking for something, but does not know exactly what, browsing through a journal can lead to serendipitous discoveries. In "the old days" when one would actually go to the library and then browse through journals or books near to one another, interesting finds could be made. So far, this is difficult to do using electronic searches. All of the journals allow browsing electronically through the tables of contents ... call me old-fashioned ;-)
