The sidebar every journal builds by hand, done properly
Most journals paste indexing logos, ISSNs and calls for papers into Custom Block HTML, and it rarely looks right on a phone. AT Journal Blocks gives you four ready-made sidebar blocks that follow your theme, work on any screen size, and are filled in from a simple settings form.
The four blocks
Indexing logos: list the services that index your journal by name, with an optional logo you upload and an optional link. A logo is shown when you add one, otherwise the name appears as a neat text tile. Grid or strip layout. Nothing is bundled or loaded from other sites, so there are no trademark or hotlinking problems.
Call for papers: a title, short text, the deadline with a "Closes in N days" countdown and a Submit your paper button to your submission guidelines. It can hide itself after the deadline.
Journal info card: ISSN (print and online), frequency, publisher, licence and language, filled in from your journal settings and editable.
Latest announcements: your newest OJS announcements as a compact list. Nothing new to maintain.
Built to be safe for indexing
What indexers read is unchanged: every Google Scholar citation_*, Dublin Core and Open Graph tag, OAI, feeds, sitemaps and "How to cite" are byte-for-byte identical with the plugin on and off (tested on every release). The blocks only add sidebar content, on article and issue pages too.
No JavaScript on your journal's pages, no web fonts, no CDNs, no requests to other sites, no tracking.
Polished rounded cards with icons, a countdown tile and calendar dates, in your theme's fonts. Light, Dark or Follow device; dark is never forced. Pick your journal's accent colour (7 presets or any hex colour) and rounded or square corners in the settings; text stays readable automatically.
Every value is escaped; logo uploads use OJS's own file handling and accept only PNG, JPEG, GIF and WebP images.
Tested on OJS 3.5 with the Default theme and the Health Sciences theme, on desktop and phone.
