The Technology of Library and Information Networks ,[object Object],Limitations Today’s Solution Impact of Solutions A. Terminals not compatible between networks Use multiple terminals $2000 to $4000 each B. Communication lines not compatible -dedicated lines not shared between networks -VAN lines not efficient -Dial-up lines very expensive Use different or redundant transmission of services Pay redundant line costs -Higher costs -Slower response time C. Network user language not compatible Learn all required languages Human limits to memory Multiple training costs D. Files and records not compatible Convert to tape Mail to users Reconvert to new file -circulation files -union catalog Added development costs Time delay for information transfer

The Technology of Library and Information Networks ,[object Object],2. Many of these offerings will have a significant impact on the services offered by libraries and the form of these services. 3. Vendors of particular service, such as circulation or cataloging, will expand their services to other areas with high overlap of services between vendors of different services. 5. Interfaces of stand-alone systems into “subnetworks,” which in turn will become larger networks and eventually part of the “national network” will continue throughout the 1980’s. 4. Vendors of different services are building interfaces between their services, sometimes creating new services. New Trends in Networking

The Technology of Library and Information Networks ,[object Object],6. Online networks are considering offering services normally considered stand-alone, such as circulation, serials check-in, local online catalogs, and regional ILL. 7. Planning of network services among users will improve as more clearly defined and technically reasonable requirements, schedules, and priorities are generated and documented. 8. As technology continues to improve in power and decrease in cost, there will be additional activities supported at the regional and local library levels. 9. The “national database” will not be a single database but rather a highly distributed and hierarchical network of databases.
