Program for the Enhancement of Research Information (PERii phase 2)

Program for the Enhancement of Research Information PERii is the second five-year phase of INASPs Programme for the Enhancement of Research Information.  The objectives of the program are to: facilitate the acquisition of international information and knowledge; improve access to research through the promotion of national and regional journals; provide awareness or training in the use, evaluation and management of electronic information and communication technologies (ICTs); enhance skills in the preparation, production and management of journals. In facilitating the acquisition of full text online journals, current awareness databases and document delivery INASP (International Network of the Availability of Scientific Publications) has been working with individual publishers, 'packagers' of information and consolidating subscription agents.

Scientific Electronic Library (Russia)

Scientific Electronic Library (Russia)A project of the Russian Foundation for Fundamental Studies
http://elibrary.ru

Resources:
Full-text electronic versions of 2200 Russian scientific journals (including 1100 open access titles).

Terms and Conditions of Access

Though most journals and databases are available to all registered organizations, some publishers only grant access to a limited number of organizations or charge fees. Any organization irrespective of its status, business area, ownership pattern or geographical location can register itself with the eLibrary.ru server. The only requirement is that the applicant organization must be an independent legal entity. Identification of an organization in the Scientific Electronic Library is performed based on the IP addresses of the organization's computers. This means that users of those computers will only get access to those information resources of the Library to which the organization has been subscribed. When entering the Library from other computers, one can use all the Library's basic features (including full-text search), except for access to full-text articles. If users connect to the Internet via a dial-up telephone line, the IP address allocated by the provider may be different for each connection session. There are two options to resolve that problem. The best one is to get a permanent IP address from your ISP. The other option is to request a range of IP addresses from your ISP from which your current ISP address will be allocated and to use both the IP address and password in the identification procedure.

Registration

Only a responsible representative of the applicant organization should fill in the registration form. The procedure is as follows:

  • the representative of the applicant organization should fill in the user registration form and organization registration form;
  • he/she should print out the License Agreement (http://elibrary.ru/agreement.asp);
  • he/she should have the License Agreement signed by the manager of his/her organization, sealed by the official seal of the organization and then sent by conventional mail or courier to Intra Center at 7A Novatorov Str., Office 107, Moscow, 119421, Russia;
  • upon receipt of the License Agreement, the organization will be granted the "Registered" status;
  • upon registration, the representative of the organization will be granted access to the "Organization Profile" section of the web site where he/she can specify the range of IP addresses for his/her organization and choose those resources from the Library's list of resources which the organization would like (and is qualified) to subscribe to;
  • for each of the ordered resources, applications for subscription will be considered by the appropriate coordinators and, in case of a positive decision, the organization will be granted the "Subscribed" status with respect to that particular resource.
