BiblioteQ
A Library Application
Document Version 1.17
BiblioteQ is a complex, highly-configurable, and mature library application. The software supports large, medium, and small institutions. Personal libraries are also supported.
BiblioteQ should be functional on any operating system where Qt 5 LTS and newer, SQLite, and YAZ are supported. BiblioteQ also supports the PostgreSQL database engine. Qt 4.8.x is considered obsolete and is not supported.
The source of BiblioteQ is available at https://github.com/textbrowser/biblioteq.
The purpose of this document is to detail the functionality of BiblioteQ. Installation instructions are not described in this document. Please refer to the Administrator Guide document for installation information.
An existing SQLite database file may be opened via two methods. The first method involves the Recent SQLite Files option of the File menu.
The Recent SQLite Files sub-menu contains a list of BiblioteQ’s recently-accessed SQLite files. If an SQLite file is selected, the specified SQLite database is opened. Please note that BiblioteQ will first close an existing database, if one is open, before opening the specified database. A Clear option is also included in the sub-menu. If Clear is activated, the list of the recently-accessed SQLite files is emptied. BiblioteQ will remove duplicate sqlite_db_ entries from the INI file shortly after the application is launched. Also removed will be entries whose corresponding files lack read and write permissions.
The second method of accessing an SQLite database is through the Branch Selection dialog. The dialog may be accessed via the Connect option of the File menu.
After opening the Branch Selection dialog, select local_db as the Branch Name. This will prepare the dialog for accessing SQLite databases. Afterwards, click on the Select SQLite Database button to launch a file-selection dialog.
For PostgreSQL databases, items may be added by administrator and librarian accounts. For SQLite databases, file owners may add items.
BiblioteQ supports books, compact discs, digital video discs, grey literature, journals, magazines, photograph collections, and video games.
To add an item, click on the Add Item tool button and select the desired category. A Create window will be displayed. Required fields are highlighted.
Multiple items may be added simultaneously.
The Administrator Browser is available if an administrator role is connected to a PostgreSQL database. The browser may be accessed via the Configure Administrator Privileges tool button.
Four roles are available. Changes must be committed via the Save Changes button.
The process of committing changes to the PostgreSQL database is as follows:
1.The table’s current state is inspected. The operator is notified of administrators without privileges as well as duplicate administrators and the process is aborted.
2.A database transaction is prepared. If an error occurs, the process is aborted.
3.Deleted accounts are removed from the admin database table as well as from the PostgreSQL database. If an error occurs with either sub-process, the process is aborted and the previous changes are reverted.
4.Existing admin table entries are updated. New accounts are inserted into the admin table. If an error occurs, the process is aborted and the previous changes are reverted.
5.Existing admin table entries are granted the specified privileges after all potential privileges are revoked. New accounts are created in the PostgreSQL database and assigned the appropriate privileges. If an error occurs, the process is aborted and the previous changes are reverted.
6.If all of the aforementioned statements execute correctly, the transaction is committed.
Please note that leading and trailing spaces will be removed from user names during the database-recording process.
A PostgreSQL account’s password may be changed via the Password Selection dialog. A password must contain at least eight characters. Guest accounts are excluded.
Click the Connect option of the File menu.
Select the appropriate non-local_db Branch Name if one is available. Provide the Password and Userid information, if applicable, and press the Connect button.
Note: The sections Accessing an Existing SQLite Database and Creating an SQLite Database cover the details of accessing and creating SQLite databases, respectively.
BiblioteQ supports PostgreSQL 8.x, 9.x, and newer. Please note that PostgreSQL 8.x has reached its end of life. Please follow the PostgreSQL-provided documentation for installing PostgreSQL. After installing the required PostgreSQL packages, please perform the following operations:
1.Create the xbook_db database via createdb xbook_db -E UTF8 or via the PostgreSQL-recommended procedure. Please note that the database name xbook_db is only a suggestion.
2.Execute createlang plpgsql -d xbook_db or the PostgreSQL-recommended procedure for adding a new programming language to the xbook_db database.
3.If desired, replace all instances of the default administrator xbook_admin in the postgresql_create_schema.sql file.
4.Log into your PostgreSQL xbook_db database and load the postgresql_create_schema.sql file via \i postgresql_create_schema.sql.
A new BiblioteQ SQLite database file may be created via the New SQLite Database option of the File menu.
After the option is selected, a file-selection dialog is displayed. An existing or a new file may be specified. A confirmation dialog is displayed if an existing file is selected.
Once the SQLite database file has been initialized, BiblioteQ will open it. If a database is already open, a confirmation prompt is displayed. If confirmed, the current database is closed and the newly-created database is opened.
Custom SQL queries may be performed via the Custom Query window.
After a successful query is performed, the main table’s columns will be set according to the query statement. Please void including columns of type QByteArray in the custom query as the associated data will burden the software.
All content, save for configuration values, is stored in the respective database. For instance, image data are stored in a database. Temporary data reside in the application’s memory space.
The Database Enumerations Browser is available to accounts having administrator or librarian privileges and is accessible via the Database Enumerations tool button. The browser contains configurable item values.
The process of committing changes to a database is as follows:
1.For each sub-panel (Book Binding Types, etc.), a database transaction is prepared. If an error occurs, the process iterates to the next sub-panel.
2.All items in the respective database table are deleted. For example, for the Book Binding Types sub-panel, all entries from the book_binding_types database table are deleted. If the process fails, changes are reverted and the process proceeds to the next sub-panel.
3.New values are inserted into the respective database table. If the process fails, changes are reverted and the process proceeds to the next sub-panel.
4.The current database transaction is committed.
To disconnect from a connected database, click the File menu. Then click the Disconnect option.

The Error Log may be accessed via the View menu. The window details critical exceptions which were raised during a BiblioteQ session. The status bar of the main window will indicate whether or not the log contains entries.
The current table view’s contents may be exported to a CSV file via the Export Table View as CSV option of the File menu.
If clicked, a file-selection dialog is displayed.
The generated CSV file will contain comma-separated values. Values which contain commas will be encased in double-quotes. For example, A book of abstract algebra,"Pinter, Charles C.",McGraw-Hill,1990-01-01,New York,2,"Algebra, Abstract.",English,0070501386,0.00,Dollar,1,Hardcover,Home,9780070501386,89035355,QA162 .P56 1990,512/.02,1,0,Original,As New,.
The first line of the generated file contains the exported view’s header strings. The exported columns are governed by the settings in Viewable Columns.
Several categories (books, grey literature, journals, magazines) include file attachments. Attached files are compressed before being inserted into the respective database. BiblioteQ utilities the ZLIB algorithm for compression.
BiblioteQ supports embedded hyperlinks when accessing PostgreSQL databases. If a hyperlink is clicked, a search is initiated using the specified text for the given category. Please note that a clicked hyperlink will not be activated if the parent widget is editable.
BiblioteQ provides an import mechanism for importing book data contained in a CSV file. Please review the Tools menu.
BiblioteQ does not impose limits on the data content. Please note that both PostgreSQL and SQLite have rigid limits. Please read https://www.sqlite.org/limits.html for SQLite details.
Generally:
•Attached files may be of any size. Please note that submitting large files will burden both local and remote queries. PostgreSQL and/or SQLite may limit field sizes.
•Infinitely-many items may be stored, although PostgreSQL and/or SQLite may prevent this.
•Pagination is implemented with the use of the LIMIT and OFFSET clauses.
•The number of PostgreSQL accounts is not limited through the software.
