The project on independent on-line library of Blackhorse Scientific Publishers has been intorduced as early as in 1999 when Blackhorse became an independent publishing house. During previous Springer time, several efforts was made to create the up-to-date scalable and relayable database. However, on that time no such similar on-line library existed in Poland. So, the new venture to offer the full text database containing all manuscripts published at Blackhorse\'s journals started in June 1999. Just amonths thereafter, Blackhorse became a registrant of The Digital Object Identifier Foundadtion, Inc. (Washington, DC) and started to collect the manuscripts accordant to the DOI standards. The special numbering system providing and assuring the full control over several manuscripts and unifing them was developed and introduced into the standarized company's workflow.
