You should begin by reading each article and starting to categorize the areas or subtopics that each covers.
For example, in doing a literature review about elder abuse, retrieved articles may have focused on different types of abuse, attributes of abused elders, or attributes of perpetrators of abuse to older people.
At the very least, be aware of the purpose, scope, and length of the literature review, as well as the writing requirements.
This requires clarifying the purpose (Is it to simply overview a broad or specific area of inquiry, or is it expected to be comprehensive or systematic? Perhaps a focus on distinct ethnicities or time periods?
Similarly, it may take you hours to thoroughly explore literature on your topic.
Most researchers will find the time spent quite interesting, though.
Sources with titles of interest and abstracts can be retrieved on the spot in some cases, marked for subsequent retrieval, and oftentimes downloaded into software such as Refworks or Endnote.
Again, you should learn about the resources available to you through your library and take advantage of the high technological services offered by your school.
If you are a student, you will be exposed to search engines and databases such as Social Work Abstracts and procedures for accessing or requesting books, journal articles, and reports that relate to your topic.
Although information is also widely available through the World Wide Web, not every site offers credible information.
