BiblioteQ strives to be a complete and thorough library management suite. For some categories (books, journals, and magazines, for example), BiblioteQ provides a mechanism for querying the Library of Congress, or any other Z39.50-capable system, via the standard Z39.50 protocol; thus simplifying the data entry process. As for database support, BiblioteQ provides connectivity to both PostgreSQL and SQLite database engines. The application shares common functionality across FreeBSD, Linux, OS X, Solaris, and Windows.
