The University of Vienna under the aegis of Prof. Dr. Hans-Jürgen Feulner and Dr. Florian Wegscheider has established a new liturgy journal under the title Ex Fonte, which is only published online in open access (i.e. for free). 

Only the first volume appeared as a digital "anthology". Otherwise, the submitted contributions - depending on the peer review process - appear within about 3 months after submission in continuous pagination per digital annual volume. So you can submit your contributions at any time. There is also no strict page limit for the contributions (between 10 and about 80 pages are possible).
