Invisible web directories consist of vast information and help me to find exact information according to your requirements. The advantage of invisible web directories is that they are limited to a particular category and offer narrow results upon search.
however there are also the cons to it. not all the databases provide the required information i need. for example, my research topic is the causes and effects of youth depression. when i try to search for effect of youth depression in lexis singapore, no relevant search results came out as the databases only consisted of law-related stuff. i had to search for other databases that fit my research topic which is very time consuming.
the reason why invisible web could be more effective than search engine is that search engine
can result in far too many results to check properly. Results
may not be in the most relevant order. Furthermore, More authorative sources
maybe buried due to lack of popularity.
Sites are randomly crawled and indexed for keywords by software. Not even google can crawl all of the web, it is too vast. RESULTS ARE NOT EVALUATED FOR quality.
b)i would use PsycARTICLES because it is related to my research topic- causes and effect of youth depression.
it has many articles related to my topic. when i click on it, it give good info.
it state that one of the cause of teen depression is income .low income lead to higher psychological difficulties. IT IS RELATED TO MY RESEARCH TOPIC
