BIBLIOGRAPHY ON THE DIFFUSION OF INNOVATIONS*
byEverett M. Rogers**
Bibliographies on the diffusion of innovations have previously
been published by the National Project in Agricultural Communications(1956)~*** the North Central Rural Sociology Subcommittee for the st~of Diffusion of Farm Practices (1956 and 1959)~ Ross (1958)~ and Lionberger (196o).

None of these bibliographies included publications inall six of the m.a.in traditions on the diffusion of innovations.
The present bibliography includes publications in each of the

major diffusion traditions~ **** and is not limited solely to u.s.
publications.

A number of items are included from diffusion researchstudies by European social scientists who were visited by the present
author in 1961.

No claim is made, however 1 that the present bibliog..

raphy approaches a total listing of all diffusion publications
available at the present time.
ELEMENTS IN DIFFUSION

There are four m.a.in elements in the a:na.lysis of the diffusion of

an innovation.
1. The innovation, defined as an idea perceived as new by the individua.l.
2.

other.

Communication of the innovation from one individual to an ..
Diffusion is the process by which an innovation spreads.

*This bulletin is a publication from Ohio Agricultural Experiment
Station Research Project Hatch 166, "The COI!llllunication Process and the
Adoption of Farm and. Home Practices. 11**Associate Professor of Rural Sociology, Ohio Agricultural Experiment Station, Columbus, Ohio.
***These references may be found in later pages of this bibliography.
****A detailed synthesis of these diffusion research findings may
be found in Rogers (1962).

3. The sociaJ. system in which the innovation diffuses. A social
sxstem is defined as a population of individuals who are functionallydifferentiated and engaged in collective problem-solving behavior. The
sociaJ. system under analysis in a diffusion study may consist of all
the fa:rmers in a .county, the physicians in a community, or the membersof an aborigine tribe.

Individuals do not aJ.l adopt an innovation at the same:tnnovativeness is defined as the degree to which an individual

is relatively earlier to adopt new ideas than the other members of
his social system.
Most of the publications included in the present bibliography an·alyzed each of these four elements in the diffusion of an innovation.

The assignment of researchstudies to traditions was somewhat arbitrary in the case of certain of
the bibliographical items, and 90 of the items could not be classified
in one of the six major traditions.
