KohaSupport Bridge-Family Concepts

Second-round exploration based on the Bridge Portal direction. These five concepts stay in the premium arch / infrastructure family, with several variants integrating book or catalog cues so the mark can feel more library-specific without losing structural clarity.

Concept 05

Bridge Bookend

A disciplined evolution of Bridge Portal using ordered lower bars with subtle spine cuts, so the mark hints at shelving, records, and bookend structure without getting too literal.

Concept 06

Open Ledger Portal

The portal arch remains dominant, but the base resolves into a restrained open-ledger spread. This is the most direct bridge between infrastructure and library knowledge.

Concept 07

Keystone Stack

The most architectural of the new set: a stronger keystone and stacked base that pushes the mark toward dependable platform / migration / infrastructure positioning.

Concept 08

Page Arch

A cleaner open-book interpretation inside the bridge family. The lower geometry reads like pages or reference leaves, while the top arch keeps the concept grounded and dependable.

Catalog Span

A wider, more horizontal evolution of the bridge idea. The segmented base suggests order, records, and span rather than a literal book, which keeps it broad and system-like.
