Registrar was software used in the personnel or human resources area of businesses. It was the first piece of software to provide HR with the ability to effectively manage training administration, booking people on courses, sending the call-up letters, and recording their attendance. Its 'killer' facility was that it enabled HR users to build their own data dictionaries without any help from their IT people. The Registrar software was created by Silton-Bookman Systems. It was launched in the USA in 1984 and became one of the leading training administration software programs on the market with over 5000 installations. It was eventually incorporated into an LMS when SBS merged with Pathlore in 2000. Therefore Registrar itself is no longer available for sale. Pathlore was subsequently acquired by SumTotal Systems in 2005.
