Databases & Athens login



This entry is about the new thing I learnt about Google and Database searching.

There are several academic databases with viewing access to millions of articles, journals and books. Some of them give readers the opportunity to view the full text material while others allow readers just a preview. The one common thing about these databases is that, unless you are a member of an institution/university community your access to their resources is limited at best. Plus, it is also considered advisable to use more than one database, as this increases your resource pool. Does this mean subscribing with as many databases? Not necessarily, with the ‘Athens login’ (Athens is an authentication system which controls access to subscribed online databases) you have access to several databases online; although, the Athens subscription and a university does not guarantee full text viewing in some cases. This brings me to proffer an alternative-GOOGLE, which would suit users with neither a university nor an Athens membership.

Google is the next best thing after the Internet. I do acknowledge that there are several shortcomings with its search algorithm (which I shall discuss later). But, for people who know little about using databases and are not members of universities nor hold an Athens login, it is very useful. I certainly do not mean the ordinary Google Search, try the Advanced search (do remember to change the parameters though). You could also try other products like Google Scholar and Google Books which allows users to search full text of books scanned by Google, converted to text and stored in its digital database. It makes access to information resources readily available at no cost to you.

 So, every other Internet user without access to databases yet, do NOT just ‘google it’, try the Advanced search, Google Scholar or Google Books.

Google & database searching - top tip!

Hello all

Today I'd like to share with you my top tip for database/google searching, based on my own experience and on what we've learnt from Alastair Allan in the past 2 weeks.

This may seem obvious to people with much experience using databases but I think it is still worth mentioning - make use of advanced search functions! Don't just type in whatever your query is into the first search box you see - always use 'advanced search' if it is available. You're not missing out on anything by using Advanced, and you may find much more (and more importantly, you stand a better chance of finding useful information). Advanced Search gives you a lot more options - for example (depending on the database you're using), it may have options to search only for certain types of information (journal articles, e-book chapters, etc); search in article title, abstract or full text; or search between certain dates only - and most databases 'advanced search' will include multiple text boxes seperated by boolean operators (AND/OR/NOT) making it easier to construct a good query. Most databases will give you a chance to 'refine' or 'edit' your search after your initial attempt - at this point you can start experimenting with different query terms - but always start from Advanced.

So to summarise - always use 'Advanced Search' in databases - you have nothing to lose by doing so!
