Digital repository provides both to the guest and the registered users the following services:

• Simple and advanced search of a Ph.D. thesis thought the fields of bibliographic records.         
• Navigation based on defined fields of bibliographic records (scientific field, educational institution, year of award, author, country, language).  
• View a digital file of a Ph.D. Thesis only for reading.

Both for searching and for browsing of a Ph.D. Thesis’ digital file, neither registration nor login are required. Registration is required only for downloading a digital file (in PDF format) of a Ph.D. Thesis.

Note: Once downloaded, this digital file may be used further with the Creative Commons license (or licenses for accompanying files) embedded in the body (in a prominent place on the first page).

Therefore, it is not necessary to be registered to this system, but it is encouraged.
