(Update on 5 March 2015: I forgot to mention the relatively new, two-year-old ASLP Journal, which focuses on special libraries.)
If you would like to see the output of Filipino librarians published in academic journals over the years (along with the output of other researchers writing about LIS in the Philippines), take a look at Library, Information Science & Technology Abstracts, which indicates that the following works by Filipino librarians were published and indexed in 2014:
Acedera, Annabelle Paredes.
Are Philippine Librarians Ready for Resource Description and Access (RDA)? The Mindanao Experience. Cataloging & Classification Quarterly (2014) 52:600-607.
Fresnido, Ana Maria Balenbin; Yap, Joseph Marmol.
Academic library consortia in the Philippines: hanging in the balance. Library Management (2014) 35:15-36.
Morooka, Kazuko; Ramos, Mila; Nathaniel, Fonseca.
A bibliometric approach to interdisciplinarity in Japanese rice research and technology development. Scientometrics (2014) 98:73-98.
