Infotrieve has acquired Ariel software from RLG, a membership corporation of research libraries, archives, and museums. Terms of the sale were not disclosed. Ariel enables academic and research libraries to electronically convey and share scanned or digitized documents, such as articles published in scholarly and professional journals, between and within institutions, in high-resolution TIF or PDF formats across the Internet. The software was developed and launched in 1991 by the non-profit RLG. The privately owned Infotrieve is a provider of on-demand article distribution services. It is also a provider of Web-enabled virtual library platforms and outsourced information services to corporate and institutional customers. Infotrieve will continue to work with RLG member libraries on additional enhancements to Ariel. Infotrieve expects to add new information management tools and features to the Ariel software that will facilitate improved interlibrary loan procedures and enterprise information sharing. Current license and distribution agreements with Ariel users will be transferred and managed by Infotrieve, as will customer support, training, billing, and other business functions. Current Ariel customers are being contacted by Infotrieve representatives.
