- Easy to maintain (e.g., modifying [[id:ccb3bc14-a801-4ed0-b066-50b1bcd853aa][File metadata]], adding more digital objects) which is the top priority.
Instituition libraries such as Internet Archive and ArXiv are the go-to examples for a long sustaining digital library.
On the other hand, personal digital libraries are basically personal information management systems where your resources are stored: documents, notes, references, and media files.
- Exiftool for annotating my files with [[id:ccb3bc14-a801-4ed0-b066-50b1bcd853aa][File metadata]].
- [[id:253c59a3-f5ba-4d77-b535-7447a512945d][Recoll]] as the search interface.
- [[id:c422175a-5b65-4311-8cc6-11efd55364e8][Org mode]] with org-roam as my personal wiki/knowledge base as my [[id:0d2264a6-e487-4761-818a-d17d2833120f][Note-taking]] system.
The digital library does not have to be integrated as the established libraries, you just have to loosely connect a system with each of the components of your library.
My digital library are fragmented with each component located in its own directory (e.g., Zotero data directory is in ~$HOME/Documents/references~, books and documents are at ~$HOME/Documents/books~, wiki at ~$HOME/writings/wiki~) but it is a non-problem for me and it is easy to solve if it's a problem.
