El consumo de la información científico-técnica por las empresas
Abstract
The use of information of the Spanish industrial firms located at the Autonomous Community of Madrid is analyzed through the bibliographic searches and copies of original documents requested to CINDOC. Subject distribution of requested documents is shown as well as the age-dependent decrease of the demand. Journal articles account for 95% of requests, their scattering, distribution by countries and obsolescence according to subjects is also determined. Industrial firms in the Biomedical and Chemical sectors are the biggest users of information , as contained in United States and Western European journals and the Spanish journals are also heavily used. More of 60% of requested articles has been published in the 90s, while only 5% were published before 1970. Highest degree obsolescence appears in Medicine, Pharmacy and BiologyDownloads
