THE LIBRARIANS WHO FORESAW THE INTERNET

 

Throughout an unusually sunny Fall in 1970, hundreds of students and faculty at Syracuse University sat one at a time before a printing computer terminal (similar to an electric typewriter) connected to an IBM 360 mainframe located across campus in New York state. Almost none of them had ever used a computer before, let alone a computer-based information retrieval system. Their hands trembled as they touched the keyboard; several later reported that they had been afraid of breaking the entire system as they typed.

The participants were performing their first online searches, entering carefully chosen words to find relevant psychology abstracts in a brand-new database. They typed one key term or instruction per line, like ‘Motivation' in line 1, ‘Esteem' in line 2, and ‘L1 and L2' in line 3 in order to search for papers that included both terms. After running the query, the terminal produced a printout indicating how many documents matched each search; users could then narrow down or expand that search before generating a list of article citations. Many users burst into laughter upon seeing the response from a computer so far away.

As part of a telephone survey afterwards, participants were asked to provide two or three words describing the experience. Of the 78 total words provided, 21 were the same adjective: ‘frustrating'. Participants had trouble signing on to the system and experienced unpredictable failures, ‘irrelevant output' and, most of all, not knowing ‘what words to use in a search'. Yet they also found the system intriguing and exciting (‘fun', ‘thorough', ‘I dig computers'), and 94 per cent said they would use SUPARS (the Syracuse University Psychological Abstracts Retrieval Service) again if it were available. Several offered to keep the experiment running past its deadline by asking their departments to contribute funding to the project.

This group of academic guinea pigs, mostly graduate students in education, psychology and librarianship, were part of a radical online search experiment run by the Syracuse University School of Library Science. SUPARS was one of many ambitious information-retrieval studies that took place between the late 1960s and mid-1970s on US university campuses. A number of factors led to the surge in this research. Developments in computer-processing capability for speed and storage had allowed academic databases and catalogues to be digitised and moved online. Computer terminals were newly modular and could be placed around campuses for decentralised access to mainframes. And military and industry funding for computer-based research was more abundant than it had ever been. Given the opportunity, academic librarians took advantage of the chance to explore this expensive new technology. In turn, universities offered unclassified environments for collaborations with corporate technology firms and military groups; SUPARS was sponsored by the Rome Air Development Center, the laboratory arm of the US Air Force.

It's easy to see why librarians of the 1970s set out to revolutionise search. Work across the academy was expanding to such a degree that, soon, there would not be enough human librarians to support all of it. Yet, to get the information they needed, researchers would face a time-consuming, physically involved process that required librarian intervention. While academic researchers could browse new issues of journals in their field, for a focused search of all that had come before they still had to consult with a reference librarian to look up the correct Library of Congress subject headings within a multivolume manual. Armed with a set of subject headings, the researcher would then search across the library catalogue for books and in citation indexes for journal articles, including subscription databases such as the Science Citation Index as well as hand-built bibliographies created by their university's subject librarians. Finally, they would physically track down the correct books and bound periodicals that included articles they thought might be relevant – if the volumes happened to be on the library shelves.

 

It's no wonder that SUPARS participants found the system compelling, despite its limitations. And given how familiar university librarians were with the challenges of search, it makes sense that the system they designed bypassed subject headings and citation indexes. What's more surprising is that, of all the online search experiments that took place during this period – including commercially focused search systems like Lockheed's Dialog, which has since become an enterprise product – SUPARS mimicked contemporary web search more closely than any other, prefiguring several primary features of web-search protocols we rely on more than 50 years later.

SUPARS and other largely forgotten systems were the forerunners of the contemporary search engines we have today. While the popular history of the internet valorises Silicon Valley coders – or, sometimes, the former US vice president Al Gore – many of the original concepts for search emerged from library scientists focused on the accessibility of documents in time and space. Working with research and development funding from the military and industry, their advances can be seen everywhere in the current online information landscape – from general approaches to ingesting and indexing full-text documents, to free-text searching and a sophisticated algorithm utilising previous saved searches of others, a foundational building block for contemporary query expansion and autocomplete. Indeed, these and many other approaches developed by campus pioneers are still used by the multibillion-dollar businesses of web search and commercial library databases from Google to WorldCat today.
