Encyclopedias - are methodical attempts to publish a summary of the world's knowledge. One of the most attractive features of encyclopedias is their ability to help users gain a basic understanding of a completely unfamiliar subject and build a framework from which more research could be done. Encyclopedias can be written for a variety of audiences and can aim to be very broad and cover almost every subject, or focus specifically on one subject. Handbooks - are guides on a specific topic. Indexes and Abstracts - both indicate where to find the original document being sought.
Abstracts go farther and provide a brief synopsis of the document's contents.
This can help users decide if they wish to continue their pursuit of the original document. Yearbooks - publish facts, events, and analysis of events of the year preceding the date of publication. Yearbooks can provide rather detailed overviews of events and are useful for analyzing changes in many segments of society. Evaluating Internet Resources Content and visual presentation are both important criteria for deciding how useful a Web site will be. In this outline, however, greater weight will be given to assessing the value of the information presented and other helpful considerations.
