Sitasi sangatlah penting untuk penulisan ilmiah atau populer. Saat ini hanya tersedia format daftar pustaka dengan berbagai style sperti APA atau MLA pada bagian sitasi slims.

Diperlukan fitur download dengan format bibtex agar sitasi dapat diolah menggunakan reference manager tools seperti mendeley atau zotero.

berikut cara menambahkan kode

1. Ubah isi file apa_style_template.php yang terletak di template\default\citation dengan code di bawah ini
2. lalu save
3. Nimati fiturnya di bagian sitasi pada OPAC

Code

Hasil file berupa bibtext dengan format .bib

Jika dibuka akan seperti ini (contoh)

@book{bibtex_entry,
        author = {G., T., A.},
        title = {The organization of information},
        year = {2004},
        edition = {2nd ed.},
        language = {English},
        address = {Westport, Conn.},
        publisher = {Libraries Unlimited},
        isbn = {1563089769},
        pages = {xxvii, 417 p. : ill. ; 27 cm.},
        abstract = {A basic textbook for students of library and information studies, and a guide for practicing school library media specialists. Describes the impact of global forces and the school district on the development and operation of a media center, the technical and human side of management, programmatic activities, supportive services to students, and the quality and quantity of resources available to support programs.}
    }

dengan file .bib dapat diimpor ke mendeley atau zotero.
