Ebib is a BibTeX database manager for GNU Emacs that provides a standalone interface for managing bibliographic references without editing raw .bib files. It features a two-window layout (index and entry buffers) and supports both BibTeX and biblatex formats. The system enables entry creation/editing, search/filtering, citation insertion into text buffers, external resource linking (files/URLs/DOIs), notes management (Org/Markdown), reading list tracking, and keyword handling. Built entirely in Emacs Lisp, it integrates with Emacs ecosystem tools like Ivy/Helm for completion, Org mode for notes/reading lists, and external utilities for DOI resolution and file viewing. The architecture is modular with separate modules for database logic, utilities, filters, notes, reading lists, and keywords, demonstrating good separation of concerns.
