Question

In such a changing society simple ways to solve problems in the past to informational needs become difficult．Many of life's problems which were solved by asking family members, friends or friends are beyond the ability of the extended family to settle．Where to ask for expert information and how to determine which expert advice to accept are questions facing many people today.

Besides this, people have kept moving since World War Ⅱ．As families move away from their home-towns, their friends of many years, their extended family relationships, the informal flow of information is cut off, and with it the belief, that information, will be got when needed and will be trustworthy and believable．The almost unfelt flow of information about the simplest fields of living can be cut off．Thus, things once learned through the daily communications of the extended family must be learned with intention.

Adding to social changes today is a huge inflow of information．Any person now can get more information than any generation, and the task of finding that one piece of information connected with his or her particular problem is difficult, time-consuming and sometimes even too huge.

Together with the growing quantity of information is the development of technologies which make people able to store and deliver more information with greater speed to more places than it has ever been possible before．Computer technology makes it possible to store vast amounts of data in machine-readable files, and to program computers to find specific information．

Telecommunications developments make the sending of messages via television, radio possible, and very shortly, electronic mail to bombard people with huge numbers of messages．Satellites have extended the power of communications to report events at the instant of occurrence．Expertise can be shared worldwide through teleconferencing, and problems in dispute can the settled without the participants leaving their homes and or jobs to travel to a distant conference site．Technology has facilitated the sharing of information and the storage and delivery of information, thus making more information available to more people.

In this world of change and complexity, the need for information is of greatest importance．Those people who have accurate, reliable up-to-date information to solve the day-to-day problems, the critical problems of their business,, social and family life, will survive and succeed,  "Knowledge is power" may well be the truest saying and access to information may be the most critical requirement of all people.
