Beginning in the 1960s with the development of the machine-readable catalog record (MARC), the process of automation has expanded to include the core functions of acquisitions, cataloging and authority control, serials control, circulation and inventory, and interlibrary loan and document delivery. The library automation field is currently dominated by a handful of systems vendors (Auto-Graphics, EOS International, Ex Libris, Follett, Innovative Interfaces, Polaris Library Systems, SirsiDynix, TLC, and VTLS).
Recent trends in library automation include the growing importance of "add-ons" mostly related to the delivery of digital content (link resolvers, portal and metasearch interfaces, and e-resource management modules often provided by third-party vendors), better integration with the Web environment (rewriting fat PC clients as browser applications, using XML and style sheets for display, and developing XML import and export capabilities) and for academic libraries, closer integration of library systems with learning management systems.
The initial work on library automation began in 1930's when punch card equipment was implemented for circulation and acquisition in libraries. During the 1930's and early 1940's progress on computer systems was slow because of depression and World War II. The library automation progressed along with the developments in computer and communication technology. The landmark developments in history of library automation are as follows:
• From 1946 to 1947, two significant computers were built. The ENIAC I (Electronic Numerical Integrator and Calculator) computer was developed by John Mauchly and J. Presper Eckert at the University of Pennsylvania. It contained over 18,000 vacuum tubes, weighed thirty tons and was housed in two stories of a building. Another computer, EDVAC, was designed to store two programs at once and switch between the sets of instructions.
• A major breakthrough occurred in 1947 when Bell Laboratories replaced vacuum tubes with the invention of the transistor. The transistors decreased the size of the computer, and at the same time increased the speed and capacity.
• The UNIVAC I (Universal Automatic Computer) became the first computer using transistors and was used at the U.S. Bureau of the Census from 1951 until 1963. Software development also was in progress during this time. Operating systems and programming languages were developed for the computers being built.
• Invention of integrated circuit by Robert Noyce of Intel and Jack Kirby of Texas Instruments in 1960s can be considered as yet another landmark. All the components of an electronic circuit were placed onto a single "chip" of silicon.
• Development of a new indexing technique called "keyword in context" (KWIC) by H.P. Luhn, in 1961 for articles appearing in Chemical Abstracts. Although keyword indexing was not new, it was found to be very suitable for the computer as it was inexpensive and it presented multiple access points.
• Use of computer for the production of machine readable catalogue records by the Library of Congress (LoC) in mid-1960s. Between 1965 and 1968, LoC began the MARC I project, followed quickly by MARC II. MARC was designed as way of "tagging" bibliographic records using 3-digit numbers to identify fields.
• The MARC II format became the basis of a standard incorporated by NISO (National Information Standards Organization) in 1974. This was a significant development because the standards meant that a bibliographic record could be read and transferred by the computer between different library systems.
• ARPANET, a network established by the Defense Advanced Research Projects Agency in 1969 brought into existence the use of e-mail, telnet and ftp.
• The use of commercial systems for searching reference databases (such as DIALOG) began in 1970s. BALLOTS (Bibliographical Automation of Large Library Operations) in the late 1970's was one of the first and later became the foundation for RLIN (the Research Libraries Information Network).
• The On-line Computer Library Center started its first cooperative cataloguing venture in 1970s. This significant project facilitated technical processing of library materials in member libraries.
• A sub-net of ARPANET made MELVYL, the University of California online public access catalogue, available on a national level in 1980. The MELVYL is still used as centralized integrated library software by all the campuses of University of California.
• During 1980s, the size of computers decreased, at the same time, technology provided faster chips, additional RAM and greater storage capacity. The use
of microcomputers during the 1980's expanded tremendously into the homes, schools, libraries and offices specially in developed countries.
• The UNESCO started distributing Micro CDS / ISIS in 1980s through its distribution centre in every developed country. Free availability of Micro CDS / ISIS, developed specially for library applications, proved a boon for the librarians in developing countries.
• Several integrated library package started appearing in the market place. The LibSys in India was launched towards the end of 1980s.
• In 1980s, several other software became available to librarians, such as spreadsheets and databases for help in library administration and information dissemination.
• The introduction of CD-ROMs in the late 80s changed the way libraries operate. CD-ROMs became available containing databases, software, and information previously only available through print, making the information more accessible.
• Connections to "outside" databases such as OCLC, DIALOG, and RLIN continued, however, in the early 90's the databases that were previously available on-line became available on CD-ROM, either in parts or in their entirety. Libraries could then gain information through a variety of options.
• The Internet gave rise to yet another era in library automation. The use of networks for e-mail, ftp, telnet, Internet, and connections to on-line commercial systems grew.
• The World Wide Web developed in 1993 became the fastest growing media of information delivery of all kinds.
• Expert systems and knowledge systems became available in the 90s with improvement in software and hardware capabilities. With the development of more advanced silicon computer chips, enlarged storage space and faster, increased capacity telecommunication lines, the ability to quickly process, store, send and retrieve information is causing the current information delivery services to flourish.
